DW300 Fuel Pump, Delphi 1000cc Injectors - do I need a FPR? Evo V
Hi everyone,
Im looking at running this fueling setup for my evo V.
DW300 (340?lph)
Delphi/Precision 1000cc injectors
Stock ECU remap
Will I need a Fuel Pressure Regulator? I've searched and come up with some saying the fuel pump might overrun the stock FPR, and some say that the larger injectors need a FPR?
Thanks!!!

I ran a similar setup on my evo 4 forged stroker motor, I had no FPR but it was not going to run right on a remap so i went for a link ecu. If your going to play around with those mods get an aftermarket ecu or its kind of pointless.
Older but proven tech
