I just tried bypassing the solinoid on the valve cover and it didnt do much. The car is pushing about 5lbs of boost. I am going to check all the bolt on the turbo and reconnect the exhaust elbow too.........make a new seal......leaking a little bit. I just ordered a up pipe from ATR so that will be taken care of. I put the fuel pressure up to 40 line off and the damn thing started stumbling again. SO now she is at about 37 to 38 with line off. And is running good through the gears with the 5lbs of boost. I think the up pipe is killing my boost!! You guys are right about the turbo noise...........even with no boost it is whistling!! I like it. I think I take care of the up pipe and I should be on my way. Later Nick
