Hello, my name is nathan. I have a base grand prix 2007 and just want to know if theres any way I can convert it into a gt some how? I really want to tune my pcm but can't unless its a gt. They said maybe if I concert it into a 2004 gt pcm but I don't know where to start. I have some minor mods. Custom high flow air intake, polished ported exhaust manifolds, dual exhaust, msd coil packs, prj spark plug wires and ngk spark plugs. I want big stuff just need to tune. Can some one help me I love my grand prix I'm a pontiac fanatic. Just want to mod!
 


What he means Nathan is that the MSD coils have been known to look nice while causing misfires as early as two months after purchase and at most a year. You'll get bad performance from them.
