I conducted an experiment today. I disconnected and plugged the MAP line to the waste gate to see if my car was capable of generating more than .7 bar unregulated, it does not. With the wastegate disabled, I still get no more than .7 bar boost. My O2 sensor is indicating .970 volts under full boost which should be reasonably close. Is it possible the turbo itself is failing? It doesn't smoke or make any unusual noises. Is there anything else that would limit the boost/power output? I'm still stumped.
