GenIV FFV: External FRP for under 10PSI? Bought a Trick Turbo kit for my bone stock 2012 Sierra 4.8 Flex Fuel... I understand the factory pump can make some power, but what about the factory FPR at low boost levels? DO I have to start with an external FPR at the 6-10psi range?
I would like to get the kit installed and running on the factory fuel setup, whil doing my TH400 swap and moving to bigger injectors for an e85 tune...

Theory- Your should use a boost referenced FPR any time you have boost since your fuel pressure will not be whats at the rail since boost in the intake will push back against the fuel.
Reality- For that power level, you're fine with the factory FPR with a good tune.
