changing fuel pressure
I have a 2003 fx4 5.4 with a k&n cai edge evo tunner and a custome exhaust I was wondering if I get a fuel pressure regulator and turned the pressure up if I would see an increase in power or would i need to get bigger injectors

Fuel pressure is already regulated.
Bumping the pressure, or larger injectors, just upsets the apple cart - with no way for you (with your current mods) to properly compensate for it. And no basis at all - again with your current mods - to require it.
You wanna run too rich on purpose?
