Do the OSID's on GTPs without Performance Shift have the Performance Shift tables setup up? On the Impalas, Performance Shift and Normal have identical values in the tables.

Nevermind: I just looked at a stock 2002 GTP bin and they do have different values. The Performance Shift tables are not that aggressive, but they are different than Normal.
Well yeah GM is not gonna put massively different settings in the peformance shift. I think they mostly took off the speed limiter, and changed some shift points to hint at more spirited shifting, but nothing crazy.

Of course you are gonna seek out people in the community who have redone their tranny tunes and get their profiles to make a better performance shift tune. I have Chris O's tune he uses on his GTP, different shift points and such beyond what the stock performance shift has to offer
