ok here is my fuel setup for turbo so far, 450cc DSM injectors with resistors, Apexi VAFC, missing link check valve. VAFC controls the injectors now i need control pressure. My question is do i need FMU or FPR? between FMU and FPR which one is better. 12:1 FMU can be called that it automatic self adjust the pressure by per boost. FPR needs to set pressure needed. i dont know how many psi need to set for FPR.

 

you dont need the missing link or the fuel pressure regulator stock is fine
