The size of the LT4 HPFP bore is likely not big enough to handle more volume, even at lower pressures, so in that scenario you might as well run higher pressure since it helps the injectors flow more.
At the end of the day, you’re on the right track. Keeping the IPWs in check is the name of the game. Rock solid low side pressure and bigger injectors are the foundation and the one variable you can mess with is the HPFP pressure, if you’re running the LPE version.

So, even if my rail pressure fluctuates, as long as the IPW's are in the 5's, I can not be concerned?
