I loosely understand that you can kind of "cheat" smaller injectors into thinking they are larger ones by bumping up the pressure differential between the fuel pressure and the manifold pressure, but if I'm already running large enough injectors, do I really need to bump up the pressure?

Like dorkidori said, you'd need one when you run a larger fuel pump than stock. And as far as I've seen, all aftermarket FPR's are adjustable.
