Anyone install PI intake without a tune? i have thinking about putting the pi intake on my car but if it will need a tune i'm not ready to spend that much money right now. So how many people installed the intake and its running fine without a tune.
It would be perfect is anyone has had their car on a dyno and checked the a/f ratio with the intake.
