im not boosting anything passed 5psi i have a manual boost controller and for some reason it wont go passed 5psi i want to run 8psi on a dailydriver
Sounds like you just got a vacuum/boost leak somewhere.
well i hope so cuz this is pissing me off
your MBC may be hooked up wrong? maybe its messed up? if your getting 5 psi I doubt its a boost leak.
