Alot of Katy guys here. lol
I really like the E85. Its 105 octane so yes it will get less milage in our low compression motors, but if you ran a motor with 11:1 you would get as good as stock milage. The high compression takes agvantage of the higher octane where the lower compression cant effeciently use the higher octane. E85 is also a much cleaner burning fuel and has nearly no deposits like gasoline.

I took a trip over the weekend with the idea of runing E85 the whole way. The first tank got me 17.4mpg. After that tank I ended up putting 5 gallons of premium back in to get me to the next E85 station since the one I stopped at when I was real low had run out of E85. After that though I refueled with E85 and have been getting what I would guess to be around 16-17mpg still. There was alot of highway driving on the first tank, about 80%. Since then I've been running alot of everything kind of driving. After gas prices went up 30 cents in one day around here I plan to keep running it and tune for it.

I just looked and there's a bunch of stations here in town! There's on my way home from work too. $2.65/gal
So basically with 91 octane at $3.19/gal here at 17mpg I would break even if I get around 14mpg with E85.
Zippy, what did you do to tune it exactly? What's your target AFR while cruising and at WOT?
