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

There are 2 diagrams around here that are very helpful, if I wasn't on my really slow laptop I would find them for you but just serch turbo,vacuum,diagram and it should come up, Vadim posted it I think...

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).

run it off the back of the intake manifold and use a dedicated line
