I have just recently finished building my 6.0 fully fordged 317 heads truck intake and a on3 78/76 for my 02 tahoe. I am trying to figure out if i need to put a biugger fuel pump i already have a aermotive stealth 340 in the tank and the truck is a factory flexfuel truck so it has return also i have fic 1000s for injectors i have not installed them. Any help would be greatly appreciated also i am looking to see if i need to swap the rails for aftermarket ones to run a bigger fuel pressure regulator. My goal is about 750 on low boost and closer to 900-1000 on high boost so all help is appreciated and im kinda new to turboworld so if my goals are un realistic let me know..
