I was told that I could cut a wire going to the boost sensor that controls the fuel shut off, but doing so will be would not be smart. (Engine may not handle it.) I wanted to cut it, so I can run 12 lbs of boost and if I get a couple more pounds due to a boost spike It would not go into fuel shut off. Not sure how much a 4g62 can handle. (I think thats what my engine is.) Its a 1.8L SOHC turbo engine.
