Hi guys, i have a ?? for you. Im wondering should i put a aftermarket adjustable fuel pressure regulator in place of my oem one? sine im running a blower and i have a fmu. Will a adj FPR let more fuel pass?

thanx.

What do you mean when i get rid of the fmu? i thought you need it? 42 lb.?

If you got 42lbers you dont need an fmu, when you get an adjustable regulator when your running bigger 42lbers and no fmu its good for tuning gives you a little something more to tweak other than pulse width and all that electronics talk makes it a lot easier on you.But if your using an fmu then i would assume you got stock heads and cam. And i would assume also you dont have bigger injectors. So you could get an adjustable which would be smart but you wont benefit much unless you get bigger injectors with no fmu. I got accel 36lbers did it to save a few bux plus i dont plan on ever stroking or going over 9 or 10 psi, but if i did it again id go to the deal center aka blueovalindustries.com and get the 39lbers and lightning maf since i ended up getting that maf anyways.

Holy ****! You're running an FMU with 42# injectors? What are you running for an engine / mods? That's a LOT of fuel.
