Not running E85 but I put a fuel pressure gauge in using Phunk's multi-adapter. I'm running aero340 fuel pump at about 9-9.5 lbs boost. I'm definitely seeing the pressure drop Seb is referring to. AFRs are solid and the venturi restriction at the pump is holding much higher fuel pressure than stock but I'm definitely dropping 10lbs under boost. Next time I drop the turbo I'll definitely be installing Phunk's S1 return system and drilling the venturi out to get pressure reading to expected 52 psi of a stock VQ.
