I have had my nitrous kit for about a year. I started with a 75 shot and then went up to the 100 shot. I had 8* of timing, and autolie 24 plugs gapped at .040. This spring/summer I am thinking of going up to a 125 shot and leaving it at that. What I want to know is what else should I do? I have a msd 6al. I am thinking the following: Upgraded fuel pump to 195 or 255lph, Autolite 23 plugs (2 degrees colder) gapped at about .035??? And some type of ignition retard to back it off when I use nitrous. Can anyone think of what else I can to do to assure it is running at its best?
