I guess if it came down to it, the programmer could just be put back to stock, then E85 could be run.

I've only used E85 one time. Wasn't worth it to me. I'm just thinkin' ahead for when the next crisis strikes and the pumps are dryin' up at the gas station.



And I did some lookin', the only programmer I saw that works for E85 is the DiabloSport Flex Fuel Predator, but it doesn't show one for Fords.
