i have a 04 grand prix gtp comp g and im looking for just some simple upgrades. intake exhaust etc. when i found this kit from 3800 performance. has any one purchased this setup and what will i need to pay attention too, (ie KR, changing plugs, which pulley size, t-stat temp, etc.) i believe the PCM is programmed to eliminate KR. any help and insight would be greatly appreciated. im a technician but im sure there are people on this board who have the mod process fine tuned haha.
this is what the stage 3 package comes with:
3.4 or 3.25 pulley
reprogrammed digital hp pcm
cat back exhaust
cold air intake
160 or 180 thermostat.
also should i be looking at any other parts to even everything out and maximize power with what i have? thanks!
