concensus is 15-17 psi, but suggestion is rewire your fuel pump.

and if you put in bigger injectors you need an aftermarket AFC of some sort. These are not cheap.

do all the other steps first. and then if 325hp is not enough, THEN go for the 550s, afc, big16g etc, etc

on this site there is a section dedicated to the correct path for upgrading. Stage 1 (300hp) and stage 2(400hp) both for 1g and 2g cars.

best of luck, and have fun.

you should put in those injectors if you already got the afc
