Which brand do you have? What kind of gains? If I were to install one, how much more pressure should I add? I have:
AC CAI
Magnecor Wires w/ Denso Plugs
Cat bypass pipe

Well you don't need a Fuel pressure regulator unless you are goin turbo, to help supply more fuel to the engine. our cars already run rich, so doing this will make it even worse!!
