Hey today i went for a cruise in my friends ls1 trans am. I was pretty suprised to feel how much power it was putting out stock. I almost was discouraged that my GTP will never make the power that his ls1 is putting out. Although i've seen a gtp beat a ws6 trans am on youtube which surprised the **** out of me. The GTP claimed to only have a full 3.4 set up. I wasn't sure if it was true. But i refuse to give up on my GTP seeing that i only have Headers and a CAI installed, plus i love my car. Can anyone give me a honest answer as to what mods it would take to keep up with a ls1 if it's possible. Because that thing can burn rubber into second gear...thanks
