I have a bone stock '02 auto GT Conv. So far I've ran a best of 14.5 at 98.
I plan on getting exhaust, intake, and a tuner or superchip to start out. My question is what kind of exhaust and intake is best for 99-04 GT's hp wise?? How much hp can I expect from intake and exhaust?? There's a guy at a local performance shop that said I can expect 25-30 hp from I/E. I'm not so sure. Also will these mods along with a tuner to firm my shifts up put me in the high 13's down here at sea level??
