i doubt that performance package will net you 120 hp increase. that setup is a joke.

you might be able to get 400 whp with $4500 on a TURBO setup, but never on a supercharger setup. if you get that far and actually make the power your transmission will blow up and youll then have to invest in a built one to take the power which will be another at least $2000.

like i said. you cannot make a reliable 400 whp grand prix for $4500. you almost need damn near $10k to do it right. buy a different car if you want that much power and want to have it run for longer than a week at a time.
