Idk about the 2.4t but it's 8-9psi on the 2.5t. I'd think they'd be the sameI can honestly say it runs better that it ever has since installation. Tightened up all of the clamps on the intake maze and installed a new MAF. Smooth idle and very little turbo lag. Does anyone know what peak boost is for stock offhand?
