I'm gonna have a 96mm pulley on for now. Next spring, I'll throw the 92mm on and dyno again. I'm getting a baseline done tomorrow. I have post maf tubes and k&n drop ins, plus the art pipes installed on a stock tune. I'll post results as soon as I can. All in all, 516whp is insane. I'd be MORE than happy with 490whp and no meth.

on a side note.. that dyno graph goes to 7800 rpm. O_o
