Sale: Weltmeister performance chip
Location: Carleton MI
Chip-24 pin 87 Carerra
I have a Weltmeister performance chip for an 87
Carrera with the 24 pin DME. Better than stock but
not as good as a Steve W chip. $95 and I will ship
to the Great 48. Pay pal OK.
Location: West Chicago Suburbs
Will the chip work in an 89 Carrera? Also, what
is better about the Steve W chip?
Location: Carleton MI
No Rossi, It will not work in an 89 because you
have the 28 pin chip. I have a Steve W chip in my
911 and it made so much more power that it will
break the rear tires loose if you are not careful.
If you are looking for more USABLE power, get a
SW chip, Dansk cat bypass, and Dansk sport muffler.
Probably cost about $800 if you put it on yourself.
BIG BIG difference and much better driveability.
sober again from the Oktoberfest, i´ve extensively
tested Your part load maps, it´s really
impressive! On wet streets it´s hard to
leave my garage without power-oversteering ;-)
I also could not hear any pre-detonations, and
the fuel consumption seems to be about 5-10% lower
than stock. I don´t know if it would make
me faster on the track or at Auto-X because of
the steep torque-gradient, but for cruising in
high gears it´s definitively better than

have been a forum "lurker" for over
a year and purchased my 88 Carrera last October.
I recently installed a Dansk pre muffler and
a Monty two in one out.
this for several weeks and noted more throttle
response and smoother idling. Today I installed
a Steve W. chip. Steve made it for the above modifications,
93 octane and raised the redline to 6850. When
we took the old chip out we found it to be an
Autothority chip (911.020.200.20). No one understands
why it has what appears to be a Porsche parts
number. The chip must be at least 10 years old
(PO didn't know he had one).
my opinion Steve's chip made a dramatic improvement
in acceleration and throttle response. I have
not been able to really test it above 3d gear
yet. It REALLY moves between 1st and third up
1988 Carrera Targa
I see the flame still hasn't extingushed. Steve
just got the chip installed today and its dead
nuts on for what I wanted smooth accelaration
from idle, strong mid range linear acceleration
and it sounds like ripping sheet from 4000- to
the stock 6550 red line/ limiter. I am very satisfied,
just hope my local supply of 93 octane lasts.
Loren dyno sheet are to sit at the bar and brag
about, seat of the pants changes are what we really
want anyhow..emotions, feelings, the rush!!

the new chip and the car started right up. Drove
the car to work with no issues. I did notice a
significant 'push' when the car was accelerated
hard. What a rush! Thanks for the quick turnaround.
and I am a technophobe, my car is completely changed
by the SW chip. The car is awesome now, where
it was sluggish and lazy before. 2000 miles since
fitting the chip. No worries here.

about the chip. It was federalized in the U.S.
with a U.S. DME which reduced it to about 200
hp. Our goal was to see if we could recover some
of the 30 or so lost hp from the U. S. emissions
changes that were lost from my 930/20 motor which
has the 10.5:1 (I think) compression ratio. Steve
took the time before I met him to "Interview"
me about how I drove the car (mostly around LA
which means lots of bumper-to-bumper traffic,
that I wanted more power mostly for pulling on
freeways, that I may, or may not, do a DE, and
that for sure I'll run 91 octane fuel or better.
new chip gives NOTICEABLY better low-mid level
performance. Because I went camping for the weekend,
I still haven't had a chance to totally try out
the new chip, but after driving the car, I think
I wrenched my shoulder reaching so quickly for
my wallet. Steve was adament when we drove around
LA that I make sure that I'm sure the chip made
a difference, and that he didn't want me buying
it for a placebo effect, or because I felt that
I had to buy it since he spent some (alot of)
time with me.

got a SteveW chip and cat bypass. I think it's
totally worth the money. There are just not a
lot of cheap upgrades for these cars, but this
is one of them. Don't expect miracles, but there
is a difference.
don't think the power is up so much as the responsiveness
and torque are better, especially in the low rev
range. I find myself cruising around at lower
RPMs. I did have the bypass pipe on without the
chip for several months, and it is the chip making
the difference. I did have the "more aggressive"
of the two factory chips that Porsche put in the
'88 cars to start with, so I'm probably seeing
the least dramatic increase of anyone. But it
was still worth it.

Cups, SteveW Chip
got in my Steve W chip and I have been very pleased.
The car runs smoother everywhere (even in warm up).
I tell a real power boost from 3500 up. In third
gear, the part throttle response is much improved.
I highly recommend his products. No detonation apparent
with 93 octane. My 84 just turned over 200K and
is running better than ever!
I can highly recommend them, very pleased! The chip
was a 84 with test pipe. I put in a 85 (with socket)
box I had. FYI, the engine has 200K with no rebuild
and normal oil consumption and no leaks/smoke, only
a 911! I took it to a DE in Oct (at the new/magnificent
Barber track) and it ran great. Can't wait to track
it with the chip.
my Chip today!
I just installed a Steve Wong Chip and went for
a quick spin just before the next snow storm arrives.
Here are some quick observations:
a smoother idle, no more 50 rpm hunt.
engine seems to "get on the cam" at a
a slight jerkyness in traffic is gone
engine does seem quicker, although I haven't installed
the euro premuffler yet, which the chip is set up
chip is well worth $280 and I'm sure there will
be more pleasant surprises when the cat comes off.
1987 Carrera Targa - 17K miles
sent me a chip some months ago for my 88 ROW carrera.
figured that for what its worth u may like to have
took me a while to get around to putting it in and
I did it the same time as getting some suspension
changes and adjusting the Wheel camber. Car was
set up quite aggressively and the changes definitely
made the car 'Roll" better so as always judging
one change when there have been a couple made is
probably not that scientific.
immediate reaction when first driving the car is
that it gets through the gears better. It feels
like it rev's alot freer and I think that I can
notice a definite difference above 5000 rpm where
there seems to be a increase on the power surge
that I used to get.
seems to drive 'lighter' at lower RPMS around town
with the motor and car not having that heavy any
reluctant feel at Low RPM's. Obviously 1st gear
is still a bit of a pig. Haven't noticed any pinging
though I doubt I would hear it with the SSI's and
exhaust. One thing that I swear has happened is
that the car seems to have a more refined and smooth
exhaust note at idle....
up my summary is that it makes the car more drivable,
with the obvious change being that the car is not
as raw as before. Previously, since it was so sluggish
down low the difference up high was a contrast.
It has been a positive addition to the car.
'88 Euro Carrera
Steve, I just got the chip that you sent and put
it in this evening. First, let me say that that
was a very fast transaction! Thanks for sending
it out so quickly. It is truly nice to deal with
great people. Oh yeah, I almost forgot, what do
I think of the chip? Well here goes. First let
me say that I have not driven the car very hard
yet as I had my son with me and I was doing my best
to be a responsible parent! The car idles much smoother
now. It used to "pop" a little bit when
I came off the throttle or down shifted and It no
longer does that.
also used to surge a little at very light throttle
while maintaining a constant speed in traffic in
second or third gear and it no longer surges at
all. That is a huge difference in itself! The car
feels stronger down low. Like I said I have not
really stepped on it so I can not comment on the
full throttle upper rev range at all but I am very
impressed so far. The car even sounds better! Your
instructions are excellent, not that I needed them-
I have owned 6 different 911s to date- so I know
my way around them well. I have spent a ton of
money improving these cars over the years and have
bad luck with other NAME BRAND chips- hence the
fact that it took me 6 mos to convince myself to
buy one! Thank the Pelican members for helping
to convince me. Of all the thousands of dollars
I have spent on brakes, suspension, light weight
body work, exhaust, intake, tires you name it, your
chip is by far the best money I have spent! I think
as long as people understand that they are not bolting
on a turbo or a sc or increasing the displacement
by 20% when they put a chip in, they will be very
pleased with your product. I only buy top quality
parts for my upgrades and your chip definitely fits
that description. I will report back to you again
if you would like after I have wrung the car out
a little more.
free to give out my email address to any prospective
customers who want some first hand info. I will
be promoting your chip enthusiastically with the
local Canada West Region of the PCA!
Cheers, Jeff A.
Kudos for Steve W
I just wanted to post my impressions of a Steve
W Chip for my 86 Carrera. I have SSIs and I believe
a Bursch muffler but had a stock chip. I replaced
the chip with Steve's custom chip for this setup
and have been very impressed. Great mid-range torque,
ultra smooth idle and she just screams up to 6850.
I may be dynoing her in a few weeks and I will post
have a Steve Wong chip in my '84 Carrera. It replaced
an Autothority chip about 6 months ago. The engine
pulls stronger in the low and mid-ranges; marginally
stronger above 6000. Just as a point of reference,
I also have a cone air intake, a Dansk Euro Pre-Muffler
and a Dansk Sport Muffler. Steve feels that with
my set-up, my engine has about the same HP as the
Euro-spec 3.2 Carreras.
to install...Steve provides excellent instructions.
Make sure you remove the negative battery cable
before removing the DME box.
do not need to remove the non-power seat...just
slide it fully aft. I do not know about clearance
issues with a power seat.
I am very satisfied with Steve's custom chips. For
the price, you can't beat it!
put a SteveW chip in my '86 about 3 months ago.
And MarcA just put one in his 3.2-engined '77.
both very happy, but I must say Marc's light car
+ SSI exhaust really flies. Marc's has a pronounce
bump in zing as you cross 4500 rpm. Mine does something
similar, but with my heavy car and stock heat exchangers,
it isn't quite as impressive. It does run much smoother
throughout the rev range and has a rock-solid idle.
more thing... SteveW is happy to tailor the chip
to your mods and the quality of gas you use.
'86 911 Coupe
Steve is the only way to go if you want to chip
the car. All of the other chips are cookie cutter,
ie every '84 gets the same chip, etc. In addition,
Steve will not increase the rev limiter above the
Club Sport limiter which is 6800 (stock is 6520)
unless you specifically ask him. Autoauthority chip
goes to 7k which will eventually cause rod bold
failure in the 3.2.
chip basically tunes the air fuel mixture and timing
taking into account the fuel and other mods, if
any, to a point that Porsche would not, and could
have given the car a pretty good work out and have
not detected any knocking or pinging, at the high
end of the rev range or when loading up the engine
at the lower Rs.
remember . . . . you will need a roll bar to track
new to this forum but I can definitely endorse SteveW
was always envious of the Euro 911 CS's because
you guys had the stock 231hp while we were stuck
with approx 217hp. After talking to Steve Darnell
and others over here I decided to opt for Steve's
chip, Dansk Euro pre-muffler, Borla muffler and
K&N filter - now I'm up to 243hp (with 91 octane)
and loving it! Now I just have to pass the smog
inspection in April - may have to do some retrofit.
ordered a chip from Steve W. the beginning of December.
I was not able to install the chip until last Thursday
night. The previous owner and myself went out for
a test ride. The po has owned the car for the last
12 years. We did our test runs and I went to the
shop, pulled the motronic out of the car. Looked
at the bottom and realized that it had already been
opened up before. Opened it and found a Autothority
chip. The po did not know about the chip. So this
chip was installed sometime prior to 1992. It is
a 1988 911 Commemorative edition. Installed the
new chip. I drove the car alone and noticed two
changes. First it was stronger from 4500 to 5800
rpm range and the sound was significantly different
beginning at 4500 rpm. Took the car back and picked
up the po and had him drive it. I didn't share what
I felt about the changes in the car. His comments
were almost identical as my impressions. Remember
he has owned the car for 12 years and knows the
car well. Next day I called Steve and talked about
the difference in the chips. If only every business
had customer service like SteveW. I was considering
returning the chip before talking to Steve, after,
I am keeping this since the chip has more safety
margin built in for bad gas, poor engine tune than
the Autothority with timing advance of up to 33
degrees and a redline of 7040 rpm. I feel thet the
safety margin that Steve has on his chip helps protect
against bad gas and marginal engine tune. There
was not significant difference in performance but
I noticed a difference and the change in sound to
a throaty growl only makes me smile more. I also
had read all the posts about how it was the placebo
affect that Lorenfb claims is the reason so many
have noticed a difference in their cars. I will
not say that there is more HP or torgue but I notice
the difference and thats what counts to me.
CE Diamond Blue Carrera
I got the chip yesterday, installed it last night.
I put my Dansk pre-muffler on this weekend also.
I'm impressed with the chip and the pre-muffler
have alot more low end hmph and seem to get up to
redline (ok, not redline, but close to it) alot
quicker than I used to. My 'bucking' at low speed/low
rpm is gone as well. I can honestly say that I do
feel a difference with chip and pre-muffler. I did
take it for a short drive w/ just the premuffler
and the chip definitely improved performance. My
Dansk muffler is on back-order, but I expect an
additional small performance gain from the increased
exhaust flow it will allow (along with some needed
'sports car noise'!!!)
many thanks !!!!!
ps - I have been comparing notes w/ a fellow Pelicanite
about the Ebay chips. I'm wondering if I can refer
him to you for a chip ?
second no third the suggestion to contact Steve
W. He stands behind his chips 100% and his prices
are very competitive. I'm more than happy with the
results I got with one of his chips.
'75 911s 3.2
my chip. Steve is a first class business man too.
- Steve W's chips are the real deal.
installed one in my '87, definitely a difference
in engine performance. I can't say the power increase
is dramatic or that noticeable on an otherwise stock
setup, but the engine runs better. The car feels
stronger in the lower power band, seems to launch
at lower rpm's, accelerates more smoothly, decelerates
much much more smoothly, idles better, and makes
downshifting to 1st at slow speeds less necessary.

installed one of steve's chips and was real happy
with it,What does he do? He found a way to improve
on his chip, and sends me the improved edition to
install all at HIS cost. You don't have to tell
me about steve w. Who else would do such a thing?
Needless to say I've got one sweet running 3.2
the stock chip in my 86 it had a noticable flat
spot in the torque curve and some surging. I put
Steve's chip in my 86. It pulls harder and those
faults described above went away. It did not take
a dyno to feel it. Trust me on that. I suppose I
could have spent about the same amount on some open
style air intake, gain a few HP and lot of impressive
intake noise. You get tired of that pretty quick.
1986 911 Coupe - Black (Named Inky)
W is certainly the one to work with. I tried another
chip with bad results. Talking to Steve, he put
together a chip specifically suiting my needs .
. . He put quite a bit of effort and time in with
me on the phone. Where else could you get that level
of competence -- and dedication
just got Steve W's chip last week, and love it.(see
my thread on Pelican board). Not sure what he can
do for Euro model, but shoot him an email--he's
always very responsive.
Why so much scrutiny over such a small $$
chip was the best mod I ever made to my car.
not like you are dumping $500 on a mod that may
or may not work. Ridiculous...dyno, no dyno, it's
whatever works best for you and your car.
seat does not need to be removed and if you don't
have to solder in a socket the first time, takes
all of about 10 minutes to change in or out.
results are outstanding, I know my car and it has
more HP. Not just seat of the pants. Steve was also
the first to make me realize that mods need to happen
as a complete system...chip, intake, by-pass, exhaust
etc. Just doing one will not yield all of your potential
gains and may actually decrease HP.
car never idled so smooth or pulled so hard in all
gears. First gear has almost become useless with
the added HP, it is simply too short and I can't
shift fast enough into second to keep up with the
cannot go wrong with Steve's chip...as many others
have said before.
