air like a compressor to find leaks. I used rubber plumbing caps from Lowes to cover both sides of boost pipes going into the intercooler. That way I am not pressuring the intake hose before the turbo. I used one of the vaccuum lines on the balance tube to pressurized. I found leaks at 15 -25 psi . One was on the boost pipe going into one of the throttle body. Hose clamp wasn't sealing correctly. I cranked it all the way to 30 psi. Noticed my Apexi BOV will not hold boost greater than 27 psi before it starts leaking.
