Any other 01 Cobras out there???

Powerstroke chips don't alter boost level, rather they alter the injection timing and fuel delivery. More fuel means more power and boost. Of course you need a free flowing way of getting it in and out (conical filter, bigger downpipe and 5 inch exhaust on big chips).

I have talked with many different calibrators and they said it depends on the car, but most of the time chips are even done conservatively by chip manufacturers. They sell chips for all cars by a base program (a "safe" program). All cars are different and by tailoring to the different needs you unlock the potential. This is especially true on modified cars with stock computers.
