I have a set of your stage 1s, I'm going to put a 38r on my truck. Will I be ok with ones or should I uprade the nozzles to 2s? If so how much would that cost. I am currently running Matts tunes.
IF you are going with the 38R, I would go ahead and upgrade the injectors and that should put you up over the 400 RWHP mark with a good HPOP and fuel pressure.
