Most people find performance shift settings great for daily driiving, and leave it on all of the time. I think having a switch though would be nice though.
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.
