For the past few weeks I did not do any modifications to the car, if anything not even drive it. Recently i noticed that the car would not past 10psi, i figure ok vacum leak since my egr is removed. I recap the vacum ports on the TB. and still nothing... My vacume on the boost gauge is around 20 at idle. I removed the line from the waste gate to MBC still not passing 10. I removed the line from jpipe to MBC... still nothing. Mind you the car was running on 15 lbs for over a year. Any suggestions??? Thanks guys!
