    Check it again I can’t tell you how many times I hear that to find it leaking like a wind tunnel.

    if your 100 percent sure it’s not leaking beyond all doubt then put a turbo on it. Something’s went through the exhaust housing.


    There’s a blue rubber line from compressor to the intake. It’s the fresh air inlet to the compressor be sure to check that. Airing up your CAC really doesn’t check for boost leaks

    When something comes loose be it a fin or a piece of anything out of the motor it ruins the exducer on the turbo. They will still make the normal psi but they do not produce the flow. That’s the bad thing about having a boost gauge. People see it and say well it made x pressure before this problem started and it still makes x pressure so it’s not air related
