jerd_hambone is right - you will never tax the stock fuel system, unless we're talking big bucks in terms of mods (in which case, you would've answered your own question already).

Else, unless you just like to waste money and show off your mods...

The handful of people who claim the PD delete caused problems probably don't know WTF they are doing or just flat out lying.
99% of the people who do...have zero problems.
Remember, the FPR itself is a PD by design.

I'd also not recommend dropping the fuel pressure just to lean out your fuel curve.
A better way of doing this is to get some kinda fuel computer (i.e. A'PEXi AFC) to fine-tune instead of broad adjustment.
Dropping the fuel pressure also degrades the fuel atomization, and you lose idle quality and sacrifice fuel economy slightly.
