My 03 GT with the MPH Mongoose kit running 10PSI has thrown this code twice when there was less then 1/4 tank of gas and I went into boost. It bogs like I'm hitting the rev limiter, then everything is fine. Fuel pressure doesn't seem to drop, and the whole thing is over in less then a second, I imagine my problem is running less then 1/4 tank and going into boost, which I remember reading might be a problem. So for now I'll just make sure i have enough fuel in it, anyone have any comments on this?
