    My o6 GP GT has a stumble @ WOT when running @ lower RPM. Looking for some advice on how to make this daily driver(which goes pretty good anyway) have better throttle response and some more power!!

    thanks for the tip on the throttle body...i checked out the thread that you recommended on "modding the 3800"...lots of info there. Want to increase performance what would be your input on the best "bang for thye buck"... PCM?

    I know your SC'd, but go turbo if you want the most out of your money.

    probably gnna stay with SC but thinkin along the lines of exhaust upgade, cool air intake, PCM upgrade and possibly smaller dia SC pulley. just want to maintain driveability daily but still kick some a$#!!

    I would read and research first.

    There is a modding thread on here that has some good info what you can do and what order. Some of it is jumbled up in there, but you'll get a basic picture of what you are going to need to do.
