FRWilk chip is what I have. If nothing else, it gives you the ability to get rid of your 02 sensor and still pass inspection.

Russell Berry's 944S chip is probably one of the best from the research I've done. $175.00, and very good support from Russell. His extensive dyno runs show an overall steady increase in torque, IIRC 5-8 RWHP is gained. He has done something like 14 updates to the chip for fine tuning it to pull out the most from the car thru the revs. If anything, driveability is greatly increased and the low RPM flat spots are virtually gone.

A chip from Russell is next on my wish list.

I noticed 3 things when I installed an autothority chip in my N/A.

1. Throttle response seemed quicker.
2. The car idled somewhat better.
3. I could hit 60mph in second.

Russell Berry is a great guy to work with and his chips are worth the money.
