Thanks Jeff, I thought of activating it by RPM, but like you I was concerned about how that would work if the RPM's dropped below the setting. As of now I'm shifting at about 6500 and to tell you the truth I never paid attention to how far the RPM's dropped between shift's. I am set up though....I think? I'm running an MSD Digital 6AL and also with not having the fuel pressure gauges in the car, I have a fuel pressure safety switch inline with the dedicated nitrous fuel line, along with a full throttle microswitch on the carb.
