i am having a hart time understanding how you expect to see imporvements by adjusting fuel pressure (across the board). Without the abiulity to reprgram the ECU, any increase fuel pressure will (unless I am way off base) lead to less power due to over fueling. With as much fuel as out motor drinks, i would imagine that the WOT fuel tables are borderline rich. Plus, have you modified the enigne that is making it inhale more air? if you are't bringing in more on the intake, what are your thoughts about wanting to bring in more fuel?
Also, is our system a return-less? I have very limited experience with returnless systems, but i do know they can be tempermental.
Its possible that I am way off base here, but in my experience with PCM programming on the wife's Grand Prix, these were my observations....
