im using a 3 bar map and I even wired my waste gate shut and got a whopping 7 pounds of boost the thing spools up then just flattens out then goes down to about 5 pounds any ideas?

sounds like a hose popped almost off, just hanging by a thread. Massive BOV leak? That shouldn't do it either. Then does the turbo spin freely with your fingures? Any crap sucked into the compressor? If the wastegate is wired shut it takes out any boost control issues, gets you down to the big parts.
