First off happy fathers day 2 all the dads out there ok my question is do i need 2 run a FMU with a supercharger cause im getting mixed answers from people around my way so i wuz wondering what u guys thought i have one just dont have it on cause i have an ajustable fuel pressure regulator and figured i didnt need a FMU

 

no you can run bigger injectors, depending on your psi...I run 42's for awhile but since I have a SFMU I run it with my 42's since I'm not using 60's which I should be using......once you go to 42's the computer has starting issue nad can run rich at idle and will also hunt for idle with out a chip or PMS

 

Im running 9psi of boost with 30 pound injectors

 

I would use one..I ran 30's with 10 psi and a SFMU..now I use 42's and the SFMU with 15 psi
