It is better to have more fuel if you have more nitrous/air. Built pumps really shine at high RPM.

Stay away from peak torque, and hit it hard at 3500rpm.

Good luck!! :hug:

thanks again pat i took your advice this morning, i just put the stroker pump on 35 min ago with all day of tunning and tweaking, we made 1131 with 2 stock cp3s at 2400 pulse fuel only, changed the pump and made 1193 without changing a thing just the pump fuel only, dyno jet number was 1265 fuel, with everyones permission and thought i would like to know if i get around 1900+ with a super flow number and a dyno jet number puts us over the top is that going to be ok with everyone, its still same day tight super flow just a dyno jet number if we need it??

Pat i have a question for you, do you think 33 degrees of timing is to much at 3700 rpm to have with the amount of spray i will be running??

Your nitrous shot is going to be pretty big, right? It will cool down the charge a ton, it might "burst". So 33 sounds fine for a start point. I run about 40-45 deg after 3500, but I'm not spraying.
