I'm running a t3 .48 (t) .52(c). I am boosting, currently at 5-6 psi. But the problem is, it doesn't really hit full boost until about 4.5k I can see boost start at about 3k rpms, but still climbs all the way to 5psi at 4.5k. Why so much lag? Could it be a boost leak? restriction in the exhaust? I also have the t3 flange with the circle in the center, so I have some exhaust leak from there; could that be affecting my spool up time?
