i'm running a t25 with a 3 inch downpipe and stock exhuast. I can only push 5 psi reguardless of what i set my manual boost controller to. I have a boost leak under my bov that needs to be addressed. My question is am i topping out at 5 psi because of the leak or is it because of the stock tiny ass p11 exhuast? Thanks for the input ahead of time?
