Different shift points and curves. But i think a chip should just adjust that.
This is wierd. I was just talking about this to fellow CEGers here in MN. In the next couple of years I plan to strip down the car, rebuild it and use it as a personal squad car(when I get out of college). I plan to run the SVTF engine and trans. Being the aftermarket is huge for these cars I should be able to find some nice parts for it, since i will be transfering engine and tranny and of course PCM.
