Alright so BASICALLY all I need to run E85 is a retune. Right now my fuel system consists of 60lb injectors, KB BAP, wiring upgrade, and Aviator 310lph pump. Im running about 15psi and am around 500rwhp (haven't had it dynoed yet). Would it be worth retuning for the corn and retuning more aggressively? OR am I pretty much at my limit fuel-wise regardless of running E85?
