Should my TDC marks and adjustable cam wheels and the marks on the cover all be set at zero? i have a evo 8 with a greddy T67 and 272's cams dynoed at 410 at 92 octane. i'm just curious cause i've been hearing about +4 and -4 so now i'm confused. thanks

 

You might get more answer by posting it in Evo Engine / Turbo / Drivetrain area. Bet it's going to be moved.

 

I'm not knocking your set-up, but did you know that you can get right @ 400hp with a stock turbo and less aggressive cams on pump gas?

 

yea i know. i want to get rid of this turbo. just got 280 cams and was just running a safe tune
