timing retard and tuning I'm a bit confused here, when you run a 100 or a 150 shot you have to retard the timing (93 octane)? That sux, can't I have a tune that will work N/A and on N20? I want to be able to push the button when those pesky Vipers pull up, and not have the excuse "oh you beat me 'cause i don't have race gas and I haven't retarded my timing for N20." Screw that, tell me I can have the best of both worlds. See what i'm gettin at?

Re: timing retard and tuning I dont retard my timing.I run maft and run it a little rich up top if I think im gonna spray.I have a scanmaster and set it buy that.I have sprayed 150 with no kr.
Re: timing retard and tuning The new little box from Ramchargers gives you that option. you run max timing for N/A and when the N2O is on, it retards it automatically. Nothing to change.
Yes, you are supposed to retard the timing on any forced induction. General rule for nitrous is 2*s for every 50 HP added. So on a 150 shot, you should retard it 6*s due to increased cylinder pressures. Its more prone to detonate with more timing.
