I even thought it was an exhaust leak so I replaced all my exhaust gaskets. I'm sure you know where this is going at this point, yea the stupid aftermarket brv was causing it. I just pulled them out and tested and I finally got full boost again. Moral of the story-Don't trust them. The stock ones work fine. On a side note when doing a boost leak test try moving the hoses in and out (and side to side) of the IC's. One of mine held fine until I pushed on it and then leaked really bad. So I had to take it out and clean up the sealing surfaces. Cheers
