I installed a Livernois dual pump assembly, I'm not sure if there are any setting or tables that need to be change to make the pump work properly. Per Livernois the pump will support 800rwhp I'm nowhere near that.
I am seeing the fuel pressure drop while logging and at the rail with a mech gauge. this is a 2010 L99 Camaro SS with a turbo
at 7psi the fuel pressure at the rail droops from 58 to 50 psi.
