quick question.....might sound kinda dumb but can't find this info....
if i use safc apexi unit do i still need a fmu vacuum operated?....

 

no

 

Are you asking if you can use both? If so then, yes.
But only when used correctly. If your running larger injectors and are already maxing them out, a FMU would help squeeze more efficency out of them (SP)
