also, i have the superchips programer, should i put it on the 87 octane tune and run premium still to prevent backfire, or should i leave it on 92 and use an even higher octane?
U might want to get your porgrammer reprogram for the nitrous setup..also did they put a t/a when they installed the nitrous...? a lot of programmers already bump timing so you might want to be careful...
