Been there done that, back in the late 90's early 00's. I had one it was also highly modded and tough to tune. But when it ran right it was awesome, I rebuilt it more than once, I finally got it sorted out and it left me with a TE-45, 72lb injectors, nice heads, roller cam, PTE front mount and a built Janis trans. It was capable of mid 10's with an easy lean tune. Still got a Buick though, its an old school Stage I but these days I'll stick with my AMG's they already come fast and are reliable.
