So Saturday I was driving the GN around and decided to gradually get into the throttle, boy did it feel good. So I decided to gradually get into it again and then I commence to hear this sound under the hood- it sounded like there was a balloon deflating but someone was stretching the balloon opening while the air was being let out. Then my fuel pressure gauge went from about 32lbs to 20lbs. So I drive home expecting to see the intercooler hose blown off at the throttle body and it was still intact. I was able to adjust my fuel pressure back to 32lbs but the fuel pressure seemed a little unsteady. I can't build any boost while driving or foot braking the GN. I do hear was sounds like a very loud spooling noise from the engine compartment but it won't build any Boost. I've checked the oil- no water in it, GN is not smoking, not getting hot, oil pressure is good. The puck on the TH downpipe is intact. The turbo impeller on the hot and cold side spin freely. There is some impeller movement from side to side. While trying to rotate the impeller and moving it from side to side, at the same time, the impeller gets into a bind. Need Help.
