First off I'll say like everyone else did. In a boosted application like ours, and where we run what'd i'd consider a good amount of boost in our cars often, you have to run the pump in a higher pressure range where the pumps are typically less effecient. At a base fuel pressure of 40psi, a pump will flow a good amount of fuel, and hence the reason people cometimes say if you have a 255 pump in your car, you may start to overrun the stock FPR at idle, but it doesn't matter once you start driving around. So now say you are running 20psi, you're fuel pressure just went from 40 to 60. Look at those charts and see how much less that pump flows.
Also for fun, I quoted you above. You could ask him "well what if you're planning to make 3 times the power?"
