Ok... You have allot of unkowns there which isn't a bad thing necessarily but here's the thing. I'm betting that the FMU that came with that kit is liekly a 10:1 and did not have your 36 lb injectors in mind (meaning that it will ramp up your fuel pressure too much). The adjustable fuel pressure regulator that you're talking about can help to offset that but you won't know where to set it without kowing what the AFR is at boost, part throttle, and WOT. You must have one hell of an engine and block in that car if you plan over 500HP and if that's the case and you plan on going with Aeromotive then you should consider getting Aeromotive's complete fuel system. I don't believe that the stock plumbing will handle the volume of fuel required to support over 500HP. At any rate... you're going to have to find some way to tune it once you get it all together... either by taking to someone with a chasis dyno who can tune it properly or by having at least three things to do it yourself: A wideband AFR reader, Boost/vac guage, and fuel pressure guage. Without those things, all you'll be doing is guessing.
