 A while back I asked about Performance kits for the Corrado G60. This
 is a summary of the replies I got.

 My Message:

Subject: Corrado G60 AutoThority Stage I/II kits
 Has anyone bought one of them? What is the differnece between them,
 and what do you get with them?

 The Stage II kit supposedly includes a 'smaller belt' for the super-charger
 to make it spin faster. What would this do to it? Any horror stories from
 anyone?

 Cost/dealers and horsepower gains would be great if you could list them.

Trevor,
       I have a Corrado G60, and over here in the U.K there is a company doing
similar things to what you described.  I looked into this and was told that the
kit consisted of a PROM change to the engine management system, and a
replacement (smaller) drive pulley on the supercharger shaft.  I was told that
this would result in an increase of power from 160BHP to 190BHP, and an
increase of torque from 160 lb/foot to 250 lb/foot!!!  As my car is a company
car I decided not to go ahead with this, but I was assured that there would be
no long term damage to the super-charger if I did make the change.


Hope this helps,

Subject: G60 chips
From: C Hapeman <[e-mail]>

I looked into things a couple of months ago.  Neuspeed was cheaper at $250,
AutoAuthority was $325, if I remember.  I called both companies up: Neuspeed
appeared very arrogant on the phone and AutoAthority was nice.  Asking for
brochures on the product, Neuspeed said our's is best just talk to those who
use us, AutoAuthority sent a letter with estimated hp and torque increases etc.
You can find their numbers in any issue of European Car.

AutoAuthority offers an upgrade policy, if you buy Stage I and later purchase
stage II you can return Stage I for a rebate thing.  I would look closely
before going with Stage II, the G-Pully change is somewhat drastic and may
effect long term engine wear.  I believe AutoAuthority also has a 30 day money
back guarantee, not sure about Neuspeed.

Stage I basically changes the gas/air mixture and some other twiks, they demand
that you run on only 92 or 93 and higher octane gas.  I believe this is way VW
didn't put the changes in the stock car, they didn't want G60's dieing at 70K
because drivers were trying to get by with cheaper gas.  Some people I talked
to said if you already use the right gas go with the upgraded chip, it will
make the car run cleaner and all in all be better for the car.

As a conclusion I couldn't get a feel for which companies' chips were better.
They do basically the same thing so my bet is they are for all intensive
purposes the same.  BTW, I'm waiting for the spring and will get the
AutoAuthority Stage I and test it out, if the change is not what I want I'll
give it back within the 30 day limit.


Please let me know what you find or get back to me with further questions.

I have Stage I from AutoThority. It's an absolute "must".  Stage II is more

similar products though their Stage II is not as good as AutoTh.

    Stage I is a chip upgrade, AutoThority's Stage II is a smaller G-60
pulley, high pressure fuel regulator, and chip. Neuspeed's Stage II is a
pulley, Gillet exhaust, fuel enrichment system, and lower temp fan switch and
thermostat. Neuspeed also has a chip upgrade, called the P-chip.
    Stage I from either company gives better driveability with an average
5.5 hp gain. It won't make that much 0-60 difference. Stage II provides
dramatic differences in acceleration and response, and could conceivably wreck
your warrenty if you blow the motor. I have found that the engine seems to
handle the extra power rather effortlessly, with no radical behavior
differences or temperature anomalies.

Subject: Re: Corrado P-chip

    I have a backup copy. I have heard of knock problems also with the
AutoThority Stage II. I have also heard of problems with the Neuspeed Stage II,
things like unburnt fuel coming out in flames from the tailpipe when
deccelerating. It's hard to know who to believe. The Neuspeed kit fools the the
computer into thinking it's in a cold start mode, which will deliver more fuel
but seems hokey. I think the chip is the better approach. I also plan on doing
the cam, and the AutoThority folks said they would custom tune my chip for it.
They also have exhaust and their own cam design coming in the future. I should
have the kit installed next weekend, then I'll have firsthand knowledge of what
the heck this thing is going to do to my engine (hopefully not blow it up). If
it seems dissapointing I can always return it in 30 days.
    One thing I am really itching to do is upgrade the motor to a 2 liter.
That would erradicate all torque deficiency in one fell swoop.  It would cost
some bucks though, but I would still be way under what a new VR6 Corrado goes
for.

I would disagree with John. I have a G-60 w/an AT Stage II kit and I would tell
you that it emits a much more aggressive tone when you put your foot down.
When the stock G-60 used to sound a bit strained the AT II "growls".

I would encourage EVERYONE with a G-60 to upgrade to the AutoThority Stage II
kit. I have seen no drop in MPG or rise in oil consumption. I have found that I
buy more gas because I love to drive the car. My smile has gotten twice as big
too. I would say that the only adverse affect of getting this kit is that my
wallet is $575 lighter (plus installation costs). Do it!

While I'm at it I'll plug the Neuspeed 25mm front sway bar. It fixes the body
roll of the stock G-60 and shows you what the definition of "cornering power"
is!

I will admit to lusting after the shifter and the revised spring & bushing
rates of the VR6 Corrado...

The second kit that Dave is talking about here also includes a fuel regulator
from Porsche 944s.  Couple of my friends have this stage II kit in their, and
compared to my girl friend's stock Corrado, it's just unbelievable.  There is
so much torque available at low rpms, and the power delivery is very smooth and
progressive.  They used Varicom, a car performance measuring computer, to test
0-60, and the result was 7.1 or 7.2 sec with skinny stock tires doing lots of
wheel spin.  On autothority's dyno, the horsepower increased to about 190bhp.
So, If I had a Corrado, this stage II kit would be the first thing on the
option list.

PS.  To a fellow netter who recently purchased a yellow Corrado in CA
     For some reason, I can't send mail to you.  The mailer daemon

     Autothority in Fairfax, VA, they will be glad to talk to you.

Once again, I hate to sound like Autothority salesman, but they are working on
one now.  But it's on their low prority list.  Our last VW club meeting was

Body primer followed by a gloss finish? When I was a kid, you could buy a lot
of different gloss finishes, either brush on, or spray can type. (I built model
airplanes - you could paint the model, spray it with gloss finish so the decals
would adhere, and then spray it with matt finish to provide a realistic-looking
finish).

What you describe sounds like a product called Glyptol.  It is painted onto
potentiometers and other adjustable electronic parts so the technician can tell
if someone's been fiddling with the unit.  You should be able to get it at
better electronic shops.  By the way, acetone thins it.

I'm following up to a slightly incorrect article; sorry about that.

Anyway, the timing and injection stuff can be modified by purchasing a new
Digifant (Bosch) chip from Autothority in Virginia.  Although it requires 92
octane gasoline, it does improve the performance of the engine -- and they've
reworked the throttle curve a bit to make it "feel" peppier.

You also get about 15-20% better gas mileage, as a bonus.  And you'll still
pass inspection, no problem.

They also have another chip that works in conjunction with a smaller pulley to
improve horsepower very considerably -- without radically reworking the wiring
the way the APS upgrade does.  Just replace the pulley and chip and go.  Don't
have any experience with it, though.

There are 2, two phase systems out.
One is by AutoThority the other by Automotive Perf. Systems.
They both offer roughly the same packages, each of which boost
the power, though they use slightly different methods.
Stage 1: Chip swap (about 300-400$)
Stage 2: Chip swap (other from the above), smaller pulley + more
     (another 100-200 ontop of Stage 1, with a full refund
          for stage 1 in AutoT, maybe aps)

What I have is Autotech's Stage 1 chip, and am quite happy with it.
APS recently also came out with a new "Stage 1" chip, which
may be a tad better than AutoTechs (and cheaper).
Essentially what the Stage 1 chips do is "recurve" the ignition
curves and fuel maps. The result is ca 20% more low end torque and
10% more max power.
Downside is that you have to use 92 octane gas.
Positive side: My gas mileage actually improved a bit because
I can stay in lower gears longer.
The car feels alot better at the low end, and pulls almost frighteningly
at freeway speeds.
I used Stage 1 because the car is still in warrantee, and it's
an easy and almost invisible (to a mechanic) change.
Stage 2s are very powerfull, but rumours has it about knock and
engines/G60 breaking. I'll wait for that one till they have all the
bugs worked out.

AutoThority (sp?) is in Viginia, also sells its chips thru AutoTech
(or was it Techtonics...hmmm, damn names) who are located on
Argonaut str near Costa Mesa, CA.
APS is in Anaheim, CA. See couple of the past issues of EuroCar (=VW&P),
several articles + installations there, or call the above, & they'll
fax you the specs.

Subject: AutoThority Stage II
From: [e-mail] (John Hamill)
Date: 13 Apr 1992 14:43:54 GMT

    Well, I went and installed the AutoThority Stage II kit in my Corrado
this weekend. I bought and installed this kit with some reservations and
visions of my supercharger self destructing, or maybe a piston flying through
the hood...
    I did the installation at my dad's garage with several VW technicians
watching me every step of the way (they only get to do oil changes on Corrado's
at this point of their product life) so watching someone rip apart the Digifant
computer was interesting to them. The AutoThority kit is fairly easy to install
if you have a fully equipped garage at hand, even if you don't the only thing
you need to do it is an air impact wrench. You must be careful and take your
time, you're playing with an expensive motor and delicate things.  I got the
kit installed in two hours, one hour going to changing the chip, the other to
changing the supercharger pulley and fuel regulator.
    Impressions: well all I can say is, VR6's WATCH OUT! The car will
launch explosively in all gears now at almost all rpms. The increase in
supercharger speed means that the car responds at low rpm much, much better. It
is much easier to get out in traffic now without having to floor it and wait
for the rpms to come up.
    On the highway, the engine seems to have to labor much less with the
cruise control when going up hills. The engine has more power whether the boost
is on or not, due to the higher fuel delivery and advanced timing. It feels a
lot more like driving the VR6. The big mushy spot from 1/4 to about 3/4 of the
way down on the gas pedal is pretty much eliminated. My highway gas mileage
actually went up with this kit, my city mileage still remains the same (about
20).

    Benefits:

    Throttle response immediate
    Gas mileage went up to 30.6 on highway
    More farhvergnugen
    Fairly easy to install
    Car is just as docile and well behaved when driven
    normally.
    Fewer parts to install than APS's stage II
    Kit is based on the chip, not an add-on analog
    fuel enrichment system like Neuspeed's.

    Non-benefits

    Probably destroyed any notion of a warrenty
    G-60 spinning faster - noisier, might wear out faster
    Temptation to accelerate like a bat out of hell
    Might wear out engine mounts faster, also the seat
    backs are taking more of a strain holding you up
    from the high g-forces.
    Doesn't include an exhaust upgrade

    If anyone has more specific questions, feel free to email me.  BTW, I
bought the kit from AutoTech, not AutoThority itself, because AutoTech has a
10% off sale on them right now. I called AutoThority and they seemed psyched to
support the kit, and I told them I was thinking of using Neuspeed's
supercharger cam, they said fine, let us know and we will send you a chip tuned
for the cam.  They are working on an exhaust upgrade also.

    I had a 1980 Scirocco that I went wild on too, warmed over GTI engine,
complete Suspension Techniques suspension with Boge Turbo gas shocks. That car
handled flat! I sold it to a friend of mine who loves it. I still wish I had
it.
    A fatter rear sway bar may help with the oversteer some. I would like
to try the complete Neuspeed suspension with the Bilstein HD shocks.  They
claim it's not that bad on rough roads. I think a lot of the problem is that
the Corrado sits high, lowering it should stabilize high speed cornering a lot.
After I lowered the Scirocco, it felt much better. I could put it into 4 wheel
drift and not loose control (well, I did a few times). I put 205-50-15 RE71's
with 15X7" MSW alloys on my Corrado, and it helped, the feel of the car changed
a lot. The car does lean a bit more than I would like, so I will probably
upgrade the front and rear bars, and add an upper front stress bar. Corrados
look really sharp when lowered.
    1993 Corrados are coming with the new "Plus" suspension, apparently VW
added more negative steering roll radius. The SLC really had a lot of things
changed. I'm still not decided whether to keep fixing up my G-60 or just dump
it and get the SLC, or maybe a 1993 GLX Jetta. The new Plus suspensions are
supposed to be much improved. I suppose I could retrofit it to mine if I find
an SLC in the wrecking yard.

switch Neuspeed provides in his kit are largely unneccessary. When I drove my
Corrado hard before I installed Stage II, the oil temp would hit the 220's. I
haven't seen it go higher yet. What's really amazing is that your highway gas
mileage goes up noticably. To maintain 65 mph requires a bare touch on the gas
pedal.

    I was told by a VW technician that as soon as I installed stage 1 I had
already voided the warrenty by opening the computer box, hence my decision to
go for stage II. Of course, hiding a chip change is a lot easier than a pulley,
although my engine still looks very stock to anyone not knowing what to look
for.
    I have been using natural oil, 10-40 and 20-50 up to the present
(Quaker State), and will probably switch to Mobil-1 soon. My roommate used that
slick stuff in his last oil change and said it made a difference to his engine.
I don't think I need to use it if I switch to synthetic.
    It's pretty amazing that with the extra 30 hp my engine temps still
seem the same as before. I highly recommend this kit - go for it!

    I made backups of all my chips, the original VW chip, the Neuspeed
P-chip, and my AutoThority Stage II chip. It's pretty easy if you have access
to a Data I/O or something similiar.
    Have you played with the suspension yet?

    Another thing I have is the dissassembled EPROM listings for all these
chips. It's interesting to examine the program for the 68HC11 microprocessor
and how the tuners modify the fuel and ignition maps.

In rec.autos.vw you write:

> Has anyone bought one of them? What is the differnece between them,

I sold a couple of used stage one's before (as a retailer), basically stage one
contains only a chip, but stage two contains a chip and a bunch of hardwares
like pulley, mufflers, themostate, etc..

I have heard horror stories about stage II kits overheated the charger and blew
up the engine. I only recommend chips + cams + exhuast but not the stage 2 kit.
The stage 2 kit is very lumpy when it doesn't blow up. :)

> Cost/dealers and horsepower gains would be great if you could list them.

the stage one chip is excellent, it gives a solid 11hp gain, and a 33% increase
in low-end torque (where a gain is needed most). A new Authority could cost
over $300 CND for a dealer.

A Neuspeed cam promises 15hp, and is a very mild cam, cost about $300 also

A stage II Autothority promises 27hp, and it would cost well over $1200.

A Neuspeed stage II also gives out 27hp, and it is about $800.

Frankly, I don't know whether Neuspeed or Autot. is better, I used to think
Autot. was better, but some people told me that Neuspeeds are just as good if
not better.

Hope it helps...

Subject: G60 chip

Hi Trevor,

My name is Jurgen, I thought I'd mail direct since I can't seem to post.  I
have a '90 G60 and put the auto-thority stage-I chip in this summer. So far I
have had absolutely nothing but grins from this product. A fellow I work with
has an identical car to mine (sans chip) so he keeps me honest as to my
perceived gain in performance. The biggest single improvement is bottom end
torque and the higher rev limiter allows for nice 6500rpm shifts (I haven't
tested the 7500 limit). Needless to say I can beat the stock Corrado every
time.  The only thing it's costing me so far is a little more fuel consumption.
I had originally considered getting the stage-II but was scared off by one of
the VW shops, which has seen two G60's with blown motors due to the Neuspeed
stage-II kit which uses the same smaller super charger pulley. I think the
stage-II kit's just creates too much boost at high rpm to keep the motor
reliable, then again I have no idea just how hard those guys were pushing it.
I purchased the Autothority chip for $250 and installed it myself in 1/2 hr,
probably the cheapest and easiest performance mod on the market (IMHO).
