Well im hopin it doesn't run that much b/c the baseline tune will just be good enough to get it to run safely with more power, then after i get forged internals i'll go back and get a more in-depth tune. There's a guy over on svtperformance whose gonna try to make it cheaper to use the 03/04 supercharger. So if he pulls it off i might go that route. Here's the link to it. http://www.svtperformance.com/forums/showthread.php?t=225887 Sounds good if it works.
