I am getting ready to install my vortech sc- kit on a basicly stock 5.0. I want to upgrade the fuel system a little before the install (even though I am using the stock pulley for 5-6psi) I want to get a dyno a/f tune shortly after the charger install, so should I get a 255gph in tank fuel pump or adj. fuel pressure reg.???.....I have full exuast and pulleys....
