yeah ive tried everything now except the ECU, all the wiring looks ok and ive cleaned all the electrical plugs. I was thinking it may have been the alarm but the way it cut out is making me think different. It was when i was driving at full boost it cut out, and i beleive that a standard ECU should not run more than 8 psi where mine was running 15psi for a little while before this happend, could this of fried the ECU??
