Planning on boosting my gsr soon...i'm gonna build the kit myself and buy all of the parts seperately. This is a much cheaper route and i'm hoping that it will work out and save me alot of money. But what do you guys think is the better way to go. An fmu which basically pressurizes the fuel more to equal the amount of boost (higher boost...higher fuel pressure) or bigger injectors? an fmu is definately the cheaper way to go but what scares me is the ratio which most of them are 12 to 1....so for every pound of boost the pressure of the fuel is multiplied by 12!....that's alot of psi
