06 GPGT WOT hesitation @ lower rpm.

[Kchase]

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!!

Clean the throttle body

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.

all depends on what your final goal is.

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$#!!

headers
plugs
intake
scan it
then tune and pulley drop

[Odi]

^^ this. make your own intake too.

[Kchase]

what heat range on the plugs and do you prefer a certain brand? should I wait on the plug change if differ from stock range until I decide on pulley drop amount and tune?

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.
