As far as performance I got apexi n1 cat back, n tech hi flow cat, m2 downpipe, and apexi intake. All of this is running on a pettit ecu...not the unlimited one. Will I be okay if I go with a fmic and fuel pump? Do I need anthing else to run safely? Thanks for your imput!

 

oh yeah, I am running 13psi right now at WOT...will I have to get better restrictor pills or what? Thanks
