Knock at 5psi?

[short_dustin]

Well I'm a big idiot I just realized the vacuum cap on the other side of the T going to the boost gauge was old and cracked and had a leak in it. I was running 26lb of boost. I can't believe I didn't tear anything up! Anyway I'm at 15 psi with NO KNOCK thank God its fixed. Thanks guys

What line did you T into for the boost gauge? a good one to T into is the line going to the MAP sensor (square box on passenger fender). The factory LED gauge gets its signal from the MAP sensor. T into this line and make sure there are no leaks near by.
