I am aware of the "flaws" - however I am more aware of quite a few people that have made well over 400whp with stock fpr, lines, fuel rail etc.
I think that your understanding of FPR overrun is flawed. It's true that you can make lots of power on the stock fpr, but that's only because when you're making big power you're using alot of fuel, at which point the over-run issue goes away.
At idle the pressure will spike because you're overrunning the fpr. Once you get into boost that is no longer the case and the pressure behaves like normal. So, you either get to assume stock fuel pressure and run rich at idle but good in boost, or you compensate for the increased fuel pressure at idle and then you run WAY lean under boost (when the over-run issue goes away). A rich idle is stinky but it won't blow up your motor...lean under boost will.
If you're dead set on running a stock fpr then get a chip set for stock fuel pressure and get used to having a rich idle. That's how your anecdotal 400whp on stock fpr was made. Otherwise, set up a variable voltage to the pump so that it isn't pushing so much fuel at idle. Either way, getting a chip burned to compensate for the increased idle fuel pressure is gonna cause you to run way lean once the over-run issue goes away under boost. I recommend against this unless you REALLY like rebuilding motors.
