I know on my Talon I run straight e85 with a aggressive timing map and 35psi of boost no detonation. Any tuners can chime in please. Can we run e85 with a more aggressive timing map on the ecoboost?? I know the truck can run e85 already. Just with the SCT and being able to save custom files..I liked to have a e85 race tune with more boost and more aggressive timing map. For those who dont know e85 is about 105 octane.. so pretty much race gas at the pump and its cheaper than real race gas and regular 93 pump gas.
