M1 single plain

flashes at about 2800, it seems like, but it really seems to vary, honestly, with the temp and how many times I run it, in a row, know what I mean? Sometimes it hits higher and harder and sometiimes, eh... but it's probably driver error, more than anything. I wanted the nitrous to hit at 3400 so I could be sure I had traction before it blasts... I want to get a progresive controller to optimize launches, but that's a ways off...
The holley ignition I have has three rev limits, one for burn out , one for launch and one overall, nice features, but I don't understand the sequences you have to choose from for the limiter, there's several types? of rev limits, I don't know how to choose which is best. Still researching that!
