Did a boost leak check for the first time today and fixed 4, but air leaks out of the throttle body... NW 90mm.....it leaks from where the throttle blade goes through housing.(circled in pic) is this normal?
Alot of air goes through it which is a leak and can draw un-metered air.......I could only see like 11psi on the boost gauge even when I cranked the air up.
