so ive been hearing a lot about e-85, and i looked it up, its 85% ethanol and 15% gas, and its 105 octane, yea i get all that, but do you have to have fuel injection or anything, or do you just fill up ur gas tank with it? sorry for the dumb question.

 

Its not a dumb question, you got to learn some how.

You need bigger injectors/255fp and you need a retune for e-85.

 

You have to be tuned for it and upgrade your fuel delivery system. You at least need a fuel pump and larger injectors.

 

I just started running it and it's great!!!

 

im close to switching myself.... lol
