I swapped motors in my daily driver, and set up a Nitrous Express Wet kit. I've been spraying a 50 shot with a window switch/wot sensor at 5,200 RPM. The phearable.net programming I am running set Vtec at 5,100 which I think is stock any ways. My question is, I know during the Vtec crossover the motor has a tendency to run a little lean. I've heard it's not ideal to spray during cross over since it's running kinda lean to begin with. The switch I am running is a nitrous outlet rpm/tps and dual stage window switch. I was thinking maybe diode isolating it, having it spray from 3,000-5,000 then again at 5,200 - 8,400, 200 rpm before my limiter. I know the Vtec dip would be hellaciously bad. Or if I could just run it from 3,000 - 8,400. I've got an AEM uego Wideband on the way, I checked all 4 plugs after spraying each time. They looked fine. To run a 75 shot do I need to start retarding the ignition? Or is stock timing okay?

I did search, this forum, and google, haven't been able to find the exact info im looking for though.

Thanks.
