E85 vs 91 for street

dstem,

You could run a FiTech FI setup and easily switch back and forth from E-85 and Fossil Fuel. Just recalc your cubic inches in the setup by plus X .30 to compensate for the consumption rate. Bingo!

I have a Ford F-150 5.0 Coyote that is a flex fuel truck. With a bunch Kroger fuel points I bought E-85 for 1.10 a gallon. It will automatically raise the HP from 360 to 375 as the ECU adjusts. I lost maybe 5 mpg. There are very few E-85 stations in Cincinnati. Also the cold start is a little bit sketchy on a new tank. I am running 93 primarily in the truck it likes that too but not as well but close per the butt dyno.
