It's an exhaust leak....I know had the same issue. Check the clamps on the piping. When I had it up on the lift ,running, I could fill the air flowing out. My vacuum pressure went from 20 to around 11. Then the other side started leaking and the boost went from 9 to around 6. You can only tighten those so much before they have to be replaced.
