While it may be the OP's issue not every H/C build need a fuel pump swap. Mine didn't, I even bought the pump but never installed it. Fuel pressure is just fine. Not that's it's gonna hurt to put one in though.

When in the 450whp neighborhood, the stock fuel pump is reaching its limits if not already at its limits. If anyone forks out the dough for a heads/cam swap and installs bigger injectors, how or why in the hell would they not upgrade the fuel pump? Even if its just for ease of mind.

Didn't feel like dropping the tank, looks like a real PITA and I don't wanna cut up on the car with the "trap door". Tuner said everythings good so I decided to leave it. Cars making good power for the mods it has so it's not struggling for fuel. I didn't disagree just said it's not absolutely necessary, and may not be the OP's problem.

I just replaced a fuel pump. Dropped the tank and put in the new one. It took a hour and 15 minutes to have the car up and running again. Had use of a lift which makes it a lot easier. No big deal to say the least.

Just picked up my car today. They rescaled the injectors and fixed the tune via Patrick G. I was not there in person due to work but let me just say what a difference!!! Runs and drives great, not stalling or idle hang anymore. No cam surge, I'm finally really satisfied. Just bought a new fax / scanner so ill upload the new graph later. Car put down just under 475rwhp and 400rwtq with the torque curve as flat as a table!! Gopro 3 black edition came in today too, can't wait to try it out!!
