Anyone do a EB tune for e85 or e85/87 mix?

As someone who just bought an F150, am I not supposed to be putting 85 in? Will I get better fuel economy going to a higher grade? I came from a focus where I just put 85 in all the time and it got great mileage. It is about 15 sents more for mid and 30 cents more for premium.
