1990 C2 - Autothority or Steve W chip?
 

I'm considering chip replacement and have read some strings about it.
Anyone out there with 964 and Autothority or Steve Wong chip?

What's your experience with either of these?

I have an Autothority in my 90 C2 specifically to better manage my LWF, so I don't stall at stop lights.

The chip was present when I bought the car, so I don't have a baseline dyno from before to compare against, so I have no idea what it did to torque/horsepower.

My engine is running a bit lean around 5k, so I plan to get the chip tuned at a dyno shop before too long.

The chip is supposed to provide a rev limiter, but it doesn't kick in until 7500rpm, so I plan to lower that as well.

Kris,
Looked at those giant sized photos of yours - What size wheel/tire are you running on the c2?
I am going to be DE-ing it soon and am looking to put stuff together.
Also, what brand of pedals are in there as well. I like the gas pedal esp - has that extra lip on the top left.
Any other mods of note?

8 and 10x18; Toyo RA-1 225/40 and 275/35.
Rennline race/dead pedals; I believe our host carries them.
Torque biasing differential from Guard. Full RS suspension w/ camber plates. Lots of weight removal (2750# w/ full tank). Weld-in roll cage. Plastic intake. Race headers, exhaust. Too many other little bits and pieces to even remember.:)

have both chips! car came with autothority, replaced it with the sw, and like it much better. if you are interested in my used autothority, i will make you a great deal so you can also try/buy both and see which you like better. i am stickin' with sw on this one.

velomann,
What's been the experience with the SW?
And let me know what you want for Autothority..

also sent you a pm...
