Hello, Im looking for some ways to get some more horsepower from my 2003
Pontiac GTP. Here is a list of things I already have in mind.
Pulley Boys Qwikchange Pulley System (for my supercharger)
A bigger Throttle Body
MSD 8.5mm Super Conductor Spark Plug Wires
MSD Blaster Ignition Coil Packs
Comp Cams Xtreme Energy L67 Cam 1
Im trying to avoid turbo's and NOS. Is there anything you guys or girls can think of that will get me more horsepower?
