To 3zercrowd and Lee, the answer is yes, if you change to an aftermarket fuel pump you are best off also installing an aftermarket rising rate fuel pressure regulator like a Sard, Aeromotive etc (not Malpassi as they suck). Dont get me wrong, its not always a necessity as it depends on how much boost and fuel you require in your application, but the factory FPR will only handle up to a certain point and usually it's not enough for what what we want. If in doubt talk to your tuner...
