Im current on the Stage2 ACN91 v310 tune and im not even close to hitting the peak boost. I top out at 8psi when peak is suppose to be 16psi( or within the plus or minus 1 psi). Anyone have like a standard procedure of where they would start to look for boost leak? It would be helpful. Thanks.

Put a boost leak tester in the inlet, cap off the vacuum lines, air it up to about 20psi and listen for a leak.. although I would guess that you're in limp mode for some reason rather than jumping to thinking boost leak. What is your DAM at, and what do your AF Learning values look like?
