maybe some help with nissans stalling are most of the cars have standard ecu and aftermarket bovs because when bovs fitted the bov stays open @ idle because of the manifold vaccum which in turn bypasses the airflowmeter and run exceessivly lean so when u up the fuel preassure may temp fix the problem to check to see if problem fixed put a 1 way chek valve on the vaccum side of bov e.g xf falcons have a 1 way valve on the carby version its green and black this stops the bov openning @ idle or when pulling up to lights and still when on boost holds the bov shut and when gears changed only lets of excess preassure and not too much boost which in return slows turbo lag. just trying to help a few nissan owners
cheers.
