What mods do you have? With a fmu I'm assuming a blower. I would get the 190/255 and fpr and still use the fmu. I don't believe I wouldn't take the fmu off and jack the fuel pressure up to 65 psi. You don't need that much pressure at idle and when you're not in boost. My .02 not knowing what you're running.
