I think he said he has a low fuel pressure safety shutoff switch on his Nitrous . This could be his problem with surging on/off. Maybe it is set too high and causing the problem. I think Monte said those cause more problems than they are worth.
Mike yep could be this.. i think now the pressure will be more consistently... switch is adjustable ? i think Yep, Monte hated those things. I've seen guys at the track have issues w/ them too. Don't run one myself.
