The other day i felt like my car (ssei) didnt have as much pep as it usually has and i glanced down and "normal shift" was on. So immediately i pressed performance shift and i felt it immediately. Is performance shift just turning on my Supercharger or just increasing the psi ..i dunno? just kinda curious what the difference was.

The main advantage in "Performance shift" it the shift points. It will let you rev higher before shifting and I believe it also downshofts easier too. Your */C and everything else under the hood is always running. It'* just how much RPM range it lets you use and when.

Normal mode LIMITS your shiftpoints, while performance mode allows it to run higher. My 93SSEi (pre-chip) shifted at the same rpm'* as Jseabert'* 93SSE without the performance shift option. Now my normal shift is shifting about where his car does because of the chip, and the performance shifts much higher.

The best way to state this is that they added the option of 'economy' shift, not performance shift.
