As many have stated though as soon as you run it and feel how much it wakes up the car you won't turn back. Here in AZ we don't even have real e85 only flex fuel which is like e54ish but still very worth it.

All this E85 and flex fuel talk makes me want to take the plunge.

I had a 93 tune with PBD, but that was brief. Ive been on an E85 tune for a bit now. The brief time I did have the 93 tune yes there was improvement, needed dialing in though the shift points weren't where they needed to be and there was some sporadic idle issues. The flex and E85r tunes I have do not have these problems.

E85 is more common than most people think. I live in a small town and i have a station within a minute from my house. I have no fear of driving hours away and not being able to find e85.
For the people that only have that available 20-30 minutes away, invest in a VP fuel can, and when you go and fill up, fill up that 6 gallon can and bring it home with you. Then you have spare just in case. When i switched to E85 i bought 3 VP cans. Mostly for when I drive to the autox track I frequent, i can bring good known E with me.

I get 17 to18mpg on dedicated e54r tune with about 50/50 city highway. I get a little lower on flex tune because I think the computer spends too much time learning after fill ups. That's calculated mileage which is always about 1mpg lower, give or take, than what the car reads.

Invest $10 in a ethanol tester too. Always test before putting some in your tank for optimal results. I keep my tester, a bottle of water and old rags in the car when I go out to get fuel.

Same here, granted that's in town and driving around the canyons aggressively. Haven't taken many long highway trips.

I get ~11.7 according to the cars mpg guage on full e85, I havent manually calculated but it could be less. I always get horrendous mpg in every car I own because I mainly drive for fun, paddle shifting and engine braking alot. I got 9.7 in my 630rwhp cts-v on e60
even on 93 I think I got 15 mpg at best.
On e85 on a 80 mile round trip highway drive I got 17.5 though. With 3.31's or 3.15s whatever the non pp1 differential gearing is, it may have been a bit better. They really should have made 10th gear a super overdrive gear probably.

So just to clarify, with a Lund (or AED, PBD) Flex Tune, that let's you run FlexFuel (the pump at my source here shows 51-83%) __or__ just straight 93, or some blend of 93 + some FlexFuel, right?
i.e., I'm assuming you just kind of fuel as you want, straight 93, Flex, a mix of both, whatever, and the ECU + the tune figures out the rest (in terms of alchy content, effective octane, etc.) As opposed to something like a full out E85/E85R type tune that can't adapt to lower octane specs.
