Nitrous Tuning

on a 100 shot you could get by with 36 degrees if 38 is best motor tune:D and good gas as long as the plug read is good then go 2 degrees every 50 which would take you to 30 at 250, but if it were me id take it to 28 on the first pass with a progressive controller(will be easier on parts and have better times once tuned correctly) then check the plug read and you may be able to bump up a couple of degrees for best times , champion makes some good race plugs you have to cross some numbers or call mrl, hughes or imm and get from them, once everything is set with a nitrous cam and convertor hold on, it will make some passes, from my nos experience you will get the most gain out of around the first 150 hp then gains will decrease some, but testing will determine what shot and progressive settings works best, a lot of trail and error , good luck
