would like to thank you for your excellent product
and first rate service. You have been helpful and
informative in your email replies to my many questions
and have made note of all my requests in customizing
my chip to my car and conditions. Your chip arrived
within 10 days of my money transfer and all without
spent the afternoon out in my car after fitting
your chip and I am impressed by the changes!
changeover of chips was straight forward and took
less than an hour. Broke one of the tabs on the
DME box but that was my fault rather than it being
due to any real difficulties.
noticed a change straight away as my car fired up
first turn on the key and normally the starter needs
a few cranks. The idle was solid and smoother than
throttle was more responsive to the touch and there
was noticably more acceleration from as low as 1000
rpm. The car now has a little extra kick from about
3000rpm which is distinct from the standard's car's
less noticable rise in power at a higher 4000rpm.
At 4500rpm the car really picks up and there seems
to be more urge right upto and beyond 6200rpm.
standard car's power output is very linear without
any real kick but your chip gives the car an "on
cam" jump in power from 3000rpm and this gives
a much nicer seat of the pant's feel of speed.
driving was improved as there is less on/off throttle
jerkyness and as there is more torque down low I
can be in higher gear at low speeds. Amazingly pickup
from 5th gear from 1000rpm was even tolerated! It
really seems improved at the low and mid range yet
the top end is better as well.
can have your cake and eat it too!
I was not sure that your chip would make much of
a difference to my car as it is a Eurospec. non
catalytic convertor engine with a Monty muffler,
running off 98RON fuel and putting out 231hp. I
suspected as unlike your 207hp. US cars mine was
the most highly tuned factory version there would
be little change in output with just a chip but
everything you said I would notice I did.
believe buying your chip was money well spent!
85 Euro Carrera
I've have regained my composure.
just hope I never get used to kick in the ass that
occurs when my foot is down and the car hits 4k.
I'm holding on for dear life, no bs. I didn't let
the needle get beyond the tach red line, but it
was still pulling like a wild animal.
improvement in throttle response, ie push the gas
pedal and I get more power. Before keep pushing
until I got more power, will help throttle steering
once I get used to the power.
telling you that the car just jumps out of it's
skin at 4k.
I couldn't be more pleased with the results. To
put things in perspective, the increase in performance
(quickness) with the chip exceeded the increase
in performance when I first put the SSIs on the
Calif. 2.7. Now that is saying something.
I installed the chip last week and drive it for 500 km and what can i say..... it´s a great chip no stalling, better responding etc. also my girlfriend on the right seat notice the difference, without i tell her something :-)thanks a lot and i will tell my 911 friends about your chips and hope they will also join the 911chips club :-)
91 964 Carrera 4 w/LWF and cuppipe
crazy fast with new chip installed. I got chip installed
around 11am Sat. morning and it fired right up.
I knew right off the bat that there was an improvement
just pulling away. There is no hesitation like before.
Once I got the car up to temperature, it was time
to have some fun. The pull was from down low all
the way to 6000's. When I really get on it in first
gear, it is so fast it is unbelievable. Grab second
and here we go again, third is a dream, just pulls
so strong and hard all the way. The sound is great
with the new MAF unit, you really can hear the engine
roaring. Temperature that day was around 35-40 F
(It actually was snowing a little bit, yuck!!) I
think we are supposed to have a few 50 degree days
this week so I get out a little more. The up and
down idle surge went away with your chip.
All in all Steve, I am very, very pleased. I'm very
much looking forward to working with you in the
next few months getting this thing twisted to the
Talk to you soon,
over there in the US,
chip arrived about ten days after your mail. Takes
a little time over the Atlantic, but I think its
reasonably fast. Fast enough for me.
took a while before I installed the chip. Didn`t
have the opportunity to try it out on icy winter-roads
anyway. A few days ago the temp was rising and the
roads cleared from the ice.
the chip went and...........I`m truly amazed ! This
was even better than I had thought it would be.
As I just have tried rolling on my 195/65-15 studded
winter tyres I have not yet tested "high speed
power" over 150 km/h. If You can achive similar
results for the 3,6 it will be a real "standard
turbo-killer" for sure.
pinging at this temperatures at least. Much smoother
and more even power delivery at WOT with no flatspots
troughout the entire revband. Much stronger both
down low and when it "transforms" to a
monster above 4500 ! No more lag. I can now pass
the crossroad- junction in 3`rd opposed to 2`nd
before. Shining even more though, is the remarkably
much better part-throttle response that is so much
better than OE (truly su...s) and FVD`s chip. Its
so much more nimble and lightfooted. Superb ! Noticeably
easier to get off the clutch without stalling, indeed
improved at takeoffs.
86 EURO 930/20 Carrera
Just thought I'd give you an up date on my 87 Carrera
Targa. Just completed a trip to Oklahoma City this
past week. I drove 1360 miles at an average speed
of 100 mph. When I could cruise without traffic
in the way I was usually between 110-120 mph. Occasionally
I would hit 140. And once I thought let's just see
how fast this car will go. I ran out of straight
road and into some traffic at 160 mph. I was at
6200 rpm's and felt I could have gotten another
10 mph out of it with the higher redline from your
chip. The car is simply awesome at that speed. Rock
solid and tracks straight as an arrow. The most
pleasant surprise came at the end of the day when
I added up all the gallons of gas and the miles
driven and discovered that I had averaged 23 mpg
driving at those speeds. The car had a fresh tune
up before the trip but I attribute the performance
to your chip. Thanks again. Even with the increased
redline I usually never take it past the red line
on my tach.
Steve Wong is my Hero
I just got around to installing my Steve W chip
tell the truth, the first 911 I drove was an SC.
Carreras' always felt a little choked in comparisson.
Not quite as revvy?
after fitting Steves' chip my car has become very
need some advice as to how to stop the smell of
burning rubber from entering the cabin???
though. The car started up and idled as smooth as
silk straight away. The installation took about
20 minutes. Great fitting instructions, including
the car, I immediately noticed that you now have
to concentrate on not going over 3000rpm during
the warmup stage! The throttle response is much
more 'on the money'. The engine feels looser (if
thats the right word?), much more willing in the
2k to 4k rev range.
best money I have ever spent on any of my cars!!!
car is totally a Stock UK spec car. No other mods
at all. Steve burnt the chip to this spec for me
and I received it in about 10 days.
only thing I had to do was adjust the idle down
slightly, which is the usual situation I believe.
this on your Christmas list. Easy to fit (even for
a monkey like me) and an amazing injection of life
into your car.
now wish that my quattro was a later model with
Motronic instead of CIS. If it were, I'd get Steve
to do a chip for that aswell!
1989 911 Euro Carrera Targa Sport(Black)
just got done with making some runs comparing
stock car with stock chip vs. yr chip. made 6-7
runs each on the same stretch of road. i chose
to compare horsepower only as 0-60 times is just
too hard to replicate and i don't want to abuse
my clutch so much. the horsepower numbers were
obtained from wot in second gear till the rev
limiter kicked in. i tried to control the other
variables as much as possible such as the amount
of gas in the tank (filled up b4 each set of runs),
and external temp was within 3 degrees. the g-tech
was set with the vehicle wt as 3000 pounds and
kept constant in its position and setting for
each run. i eliminated the highest and lowest
runs from each set and obtained the following
avg horsepower: stock chip: 174.75 your chip:
188.25! and as i said before, not only does it
show better numbers, it makes the car so much
more lively and fun to drive throughout the rpm
range which is what really counts for me. it's
idling a bit higher but is very smooth, no hunting
and no pinging that i can tell so far. the fabspeed
premuffler is going on later and i'll make more
runs in the next two days when i can get the external
temp to cooperate. btw, please feel free to share
any of this info with anyone.
88 Carrera - stock
received and installed the chip!
got back from an all too short test drive (had
to watch the big Arnold debate). First thing I
noticed was a BIG difference in throttle response
from 2000-3000rpm, much stronger in second, and
much more noticeable in third; really snapped
the head back. My son noticed it too; I took him
along for a second butt dyno opinion since he
has driven it pre-Steve W chip too. Basically
the throttle seems much more responsive throughout
the torque range and it makes heel and toeing
MUCH easier/quicker. I noticed too that at idle
the exhaust note seems a little different, more
of a cool "burble". Also I noticed that
at the lower revs I don't get any muffler back
pressure "popping", must be because
of the richer mixture. I plan to get another dyno
next week if possible, curious to see what the
HP is - will share the results with you.
ordered the Dansk pre-muffler (and gaskets) today,
should have it by Monday or Tuesday; I will probably
install it next weekend. Another dyno after that
too; maybe I'll get a quantity discount from the
dyno shop ;o) !
line, I am Very Happy with the mod - thanks! I
can't wait for my drive to the Sonoma PCA concourse
88 Carrera Club Sport (1 of 22 in the
Last night I made the first modification
to my previously stock 3.2, installing Steve's custom
chip. This was not an impulse buy--I've been surveying
various mods for a year. Pre-installation service
and communication with Steve and installation instructions
were excellent. Additionally, Steve guarantees satisfaction
with his product. I'm obviously not an hp junky
and have been pretty satisfied with my car's performance,
so Steve's guarantee made it an easy purchase. Another
advantage to this type of mod is that it's so easily
My first seat-of-the-pants impressions of
the performance gains are very positive, based on
a hour of driving around town and on the highway.
The engine pulls more powerfully from low rpms, and
feels like it gets "on the pipe" at about
3k instead of 4k. Throttle response and acceleration
are much quicker. Engine speed drops less quickly
on deceleration and downshifting. Because this is
my daily driver, I didn't want an "upgrade"
to make the engine temperamental at lower speeds.
Again, I was presently surprised. Around town, the
increased smoothness of response when depressing/releasing
the accelerator virtually eliminates the herky-jerkies
Additional considerations: Because the engine
speed decreases more gradually when you go off the
throttle, downshifting does not slow the car as quickly,
so you use more brake force. On a couple of sweeping
on ramps, when I punched it I got more front end lift
than I'm used to, resulting in noticeable understeer--I'm
glad the pavement was dry. The engine idles so smoothly
that the distinctive "percolating" sound
is tempered--I love(d) that sound, so this would have
to count as the only negative, greatly outweighed
by the advantages.
This chip has met my objective in upgrading--increasing
the pleasure of driving my car. I recommend it to
anyone with a similar interest. While my experience
is unique to my car, others have been just as satisfied,
and Steve's guarantee should make it a no-brainer.
It is a very cost-effective upgrade.
85 Targa 911
Got home late last night and as expected, your chip
was waiting. I called it quits early today so that
I could get out to the garage for the install. I admit
I was a tad nervous opening up the motronic box but
it was straight forward per your instructions.
So what I now have is stock 3.2 with the B & B
single out partnered with the Fabsport pre-muff for
exhaust upgrades and the K & N cone for improved
airflow. I just got back from 45 minutes in the foothills
for a test drive with your chip installed and I can
tell you that I am extremely impressed with the results
from the changes. I do wish I had done them step by
step to gauge which was giving the biggest return
but as a package, it really has transformed the power
characteristics. Not sure I see much around 2k like
some have said but I do notice more from 3k on up....definitely
more torque lower down in the power band and I'm attributing
that to your chip not the exhaust mods. When it hits
4500 RPM it screams! I think last time you and I talked
via email the conclusion is that my mods plus the
chip would result in 30 or so HP on top of the stock
217 and I can easily believe that 245 is where I am.
That combined with the CS's lower weight and that's
a power to weight ratio that I'm very happy with.
'88 Club Sport (1 of the other 22 in the U.S.)
trip w/ Steve W chip!
A few weeks ago the wife and I took the Pcar up
to Yosemite for the weekend.
was the first trip with Steve W's chip in the car.
Great drive up to the sierras, took 120 from San
Francisco. Fastest Ive ever gone up Old Priest Grade!
of spirited driving at altitudes from sea level
to over 8000ft.
ran great! Lots better throttle response, mid range
is stronger and !!! better gas millage!
Ive had the car Ive never been able to break the
20 mpg mark, but its been over 22 mpg and one tank
over 24 mpg!! Best Ive done since Ive owned the
are some photos I took on the trip...
is a stock 1988 Targa. Only mod is the chip, but
Im planning more!!
'88 911 targa --> fast
'61 BE35 -> faster
Well, let me tell you, this code is a winner in
my book. I have never experienced such smooth power,
idle, and response from any chip I have tried. That
includes Autothority, Weltmeister, and my own concoctions.
I see no richness at idle, even though I am at close
to 3000 feet elevation. The power band up through
4000 rpm used to sort of 'lag' with my stock chip,
but this is smooth and precise. Many thanks.
I vote SteveW, Iv not long put the chip in
my 85 euro 3.2 with sports exhaust 2 out 84mm and
K&N filter, I let Steve know what I wanted and
the gas I use, two weeks later the chip arrived
in the post with full detailed instructions on fitting.
It took me about 1/2 an hour all up and started
strait away in to a perfect idle. took the car for
a short spin and right away could fell the increase
in torque and smoooth running. ( the car ran very
well before any way) at about 2500 rpm it just pulls
away very even and quick. not unlike the 3.6 motors,
in fact some Porsche guys say it sounds like a 3.6.
The car fells lighter and more nimble, I just like
giving it gas and enjoying new ride.
back from a raod trip to France in the p-car with
the chip fitted and all went very well. On the toll
roads I was sitting on a bout 90-100 mpa and at
times up tp 130mpa and the car pulled like a train
all the there and would easly go beond that. gas
consumption was about the same, the other thing
is that it is a lot louder! more harsh sounding
at high speed.
Paul Im in the UK so SWs chip work on our
cars just e-mail the guy an get one.
85 Euro 930/20 Carrera - Channel Islands,
had Steve burn a custom chip for me several months
ago and I just got time to install it last week.
Man, what a difference! Not a huge power increase
but definitely much better overall.
car is an '88 Carrera 3.2, with Dansk euro premuffler
and Dansk sport muffler with a single 84mm tip.
The face has been cut off the airbox and it has
a K&N filter. Those changes alone provided a
very nice power boost, but the chip really woke
the car up! BTW, the car originally came with the
better "8" chip (same thing as a Club
Sport chip but with the stock RPM limit).
asked Steve to keep the timing a little on the conservative
side because I sometimes run the car in hot weather
with the A/C on, and I didn't want any preignition
issues. Many of the mass-produced chips run up to
33 degrees total advance, but we held this one to
29 degrees. Otherwise the timing is more advanced
throughout the range, and the fuel maps are richer
where needed. I also had him hold the stock RPM
limit because I really don't spend a lot of time
up around redline. Most of the chip manufacturers
get higher horsepower numbers by raising the RPM
main things I notice are:
throttle response - the engine always feels like
it's ready to go with the slightest crack of the
throttle. A lot like the Saab Turbos we've owned
for years, once they're up on boost.
power down low, like below 3000 RPM - not a lot
but definitely noticeable. It accelerates faster
and smoother from lower RPMs than it did before.
power from 3500 to redline - pulls smoother and
harder than it did before, and right up to redline.
This is especially noticeable in 4th and 5th.
the chip swap the exhaust made an occasional popping
sound on deceleration (probably from a lean condition?),
and that's gone. The exhaust note sounds healthier
no evidence of preignition, even with the A/C on
and air temperatures in the high 90's, oil temperature
at about 210 degrees.
couldn't be happier and I'd recommend Steve's work
to anyone. You can get a custom chip burned specifically
for your application for quite a bit less than what
the mass-produced chips cost.
T. - Wavey
Chip installed - car won't start
Of course the dolt (me) that installed it - put
it in backwards. So crack open the DME again -
go over it again - and wouldn't you know it -
it's in backwards!
- I'm cranking the car - it's not starting - my
wife says - how's it going to help performance
if you can't even start it?
-- Actually a Steve W chip and another happy customer
- took it for a short spin and actually chirped
the wheels from a start - my car has never done
that before - never - my four year old asked me
if that sound came from our car... Yeah buddy
- don't tell your mother...
1987 Diamond Blue Cabriolet (Fastest)
just added the Fabspeed euro pre-muff, K &
N cone filter, a B & B sport muffler along
with Steve's chip and its a different car. A friend
with another '88 did the same mods and dyno'd
it last week at 243 hp It moves the reduced weight
Carrera along quite nicely
Steve W, not only did i get better all around
performance, i am getting 50 more miles per
tank (from 300 to 350). Black magic i say, the
man is a wizard.
gas at Today's prices, the chip will pay for itself
in no time.
88 Carrera Coupe
Pacific NW PCA
just chipped my bone stock 85 Coupe with Steve's
chip. It is awesome. The "Carrera lag"
is totally gone. Much better throttle response.
Much faster and zippier, and it pulls very strongly
right to redline. He is careful to not be too aggressive
so the car will not predetonate. You'll need 91
or 92 Octane gas after chipping. It is by far the
best money I’ve spent on my car. I still grin over
the difference every time I go for a drive...
64 356C Cabriolet
85 Carrera Coupe
such a crappy day here in Toronto - so I decided
that if I can't play with my new toy, I'll start
to document all the stuff I've done to it, and stop
my lurking on this site at the same time.
is my first Porsche, a 1987 silver Targa with 105k
KM's on it. I'm the second owner - the body is perfect
- it was a total gargage queen before I got my hands
upgrades started slowly with minor cosmetics, and
ended last week with a Steve W chip - why on earth
did I wait so long!
drives great. Starts more briskly, feels smoother
and more responsive below 3K. Pulls nice and strong
to redline. What I like best is the improved throttle
response which helps the throttle blips for downshifts.
Feels more like driving my 2.0L Turbo Plym. Laser
as far as throttle response. That lag time for the
revs to come up after pushing the go pedal always
I gotta get a LSD or more tire. Tight, low speed
turns spin the inside tire more than before- much
too easy! I don't understand why LSD wasn't standard
equip. for the 911.
one more satisfied customer to your list. Money
got the chip in and it's working very well, pulling
much stronger than stock. I bought the car in late
July and it had an Autothority MAF kit with chip.
The power was nice, but the open K&N air filter
really produced lots of noise (which to some guys
feels like 10 HP or so). I put the Porsche OEM
air box and stock chip back on. I liked the quieter
sound and more secure mounting arrangement, but
did miss the power. The stock set up also seemed
to have a "flat" spot on the torque curve.
So I sold the MAF and chip for $800, bought yours
and am much happier! I feel I have gotten most
of the power that I had with the MAF kit + chip
without the noise. I doubt the OEM box is a hindrance
until I am near WOT and approaching redline. Again,
I feel you have done a very nice job providing a
high bang for buck easy to do mod without having
to make compromises.

another thumb's up for Steve W...
Put the chip in... All I can say is WOW. My car
runs very smoothly, and the pull is fantastic. I'm
very happy. Steve was very helpful up front and
the whole process was really easy. Excellent upgrade
for an 84!!!
84 Carrera Targa... Original GP White
am a lurking member of this board...but I thought
I would throw my .02 on Steve's chip. Yee Haww.
I dig it. Put it in my '84 targa today...actually
Steve helped me, muchas gracias Steve, above and
beyond the call. And this thing is great. Do not
have any statistical evidence, but empirically what
a difference for me. There is no hesitation at all
during acceleration, which I had before and it's
noticeably quicker or "peppier". Unbelievable
difference for $230...I love when you upgrade something
and it pays off this much.
gotta chime in again to agree with McG----Yee Haww
is right on! It's been a few months since Steve
put mine in, and i'm still stoked. My buddy who
was riding shotgun even noticed the change.
can not go wrong if you get a chip from Steve W.
I have had a Steve W. chip in my 86 Cab for just
over 2 weeks. Drove it to my factory today 25Mi.
there and then back on the freeway and then back
on Sunset Blvd. ( that is a great high speed curvy
road made famous in past racing songs) The thing
is it just keeps getting better. It is now sinking
in just how much better it is. On the freeway you
just hammer it and it moves. No lag at lower RPMs.
It winds right up red line and it just feels better
all over. It just pulls so much better. If the pre-muffler
and Steve W chip are a a difference of 207 HP to
235HP I am not sure, but if you go that way, you
will never want to go back. Steve’s chip is a big
bang for only $230.
Carrera Cab. Iris Blue. 7 + 9s
Your chip arrived yesterday and I installed
it this morning. Everything went fine with the installation...your
instructions were very helpful.
Car drives very nicely. Seems to pull stronger
in the low and mid-range RPM's. Top end seems about
the same as the Autothority chip I had been using.
I can see where someone installing your chip to
replace the OEM chip would really be impressed.
I'm impressed and I had a Autothority chip!
Do you have any sense for the incremental
HP gains with the euro-exhaust system, sport muffler
and your chip? I have to think that combo is probably
good for 20 HP...but you may have better data.
I received your chip Yesterday and unfortunately
had to wait until today before I could fit it.
Fitting the chip was very easy and took me about
15 minutes to do from start to finish and that included
the help or hindrance from my 2 year old son.
I really didn't know what to expect - and quite
naively I thought I would be stepping into a 996
turbo. None the less I first started with a certain
amount of trepidation and let the car warm up.
The first noticeable difference is the improvement
in idling. I had my car serviced about 500 miles
ago and when slowing to a stop, she would nearly
stall. Now she runs as she did prior to the service.
Driving around in the city she behaves very well
and in all fairness as she did before the chipping,
but I guess it is very hard to tell the difference.
The first time I opened her up was along a good
stretch of road and I needed to overtake the car
in front as this was slowing down my test run! this
is when I could feel the change. I floored it in
2nd gear at about 3000 RPM and she pulled harder
than she did before - but it got better, at 5000
RPM she was still pulling harder and when I got
to 6000 RPM where I would normally change in to
3rd she was still pulling hard - the engine screaming
behind me encouraging me to see where the rev limiter
would cut in, but I had to change to 3rd.
At that stage I Gave the infamous Porsche grin and
knew that the £150 I paid for the chip was
worth every penny!
I will keep you posted on Fuel economy and How she
handles as and when I find more out!
1987 Euro 930/20 Carrera
- United Kingdom
had a chip done by Steve a few weeks ago and just
got back from the track after the evaluation. On
top of SSI's and a sport Dansk, I have a Huntley
MAF, bored throttle body, boosted fuel pressure.
The engine itself had never been opened. The biggest
difference I noticed is the increased torque and
power going into the redline. I was hoping form
more torque below 4000 rpm but I am realistic and
know this isn't a V8. My shifting now is all over
the place at the Glen. What use to be a 3rd gear
turn now is a 4th. 3rd gear at 5000 rpm has massive
amounts of power where as before is would lumber.
Quite noticeable. I ran an authority chip prior
also, so there wasn't much else to change. Top speed
on the back stretch was up about 5-10 mph also.
