there are literly TONS of posts on here about it and an even bigger (and more technical) thread over at the HPTuners board. I'd start there.
It's 100% doable and depending on what you've done to your motor you may or may not need to move injector sizes.

your injector duty cycles will determine if you need more injector, figure 30% more fuel with e85 vs regular gas.
Also for clarification there are a few tuners who have got an actual 'flex fuel' style tune where you can run either e85 or regular, but most of the time you're locking yourself into e85 so make sure you understand that ahead of time.
Hope that helps.

"changing their fuel" isn't likely what's doing it, it's optimizing the tune for the fuel, running more timing, more boost or more compression without the negative side effects of low-octane street gas.

Im running the ms-109 raceing fuel each time I go to the track the car speeds up I was told to go to methanol to pick more hp I talk to the guy that tune my car he said that the E-85 could basiclly do the same thing an be more easier to tune.

Do not put your tune on the ragged edge while tuning with summer blend e85 and then put winter blend e85 into it!!
Good luck in your pursuit for those last tenths- e85 is a very attractive race fuel alternative.
