have you tested the BOV with an air compressor to make sure it opens and closes normally?

I run mine off of the line that comes from the manifold that goes to the brake booster. Its spliced in before the metal part in the line which supposedly has some sort of valve. Works great for me, but I'm running a greddy BOV. I have a DE+T as well (lowport).
