e85 users
I'm gonna look into an eXede piggy back with harness and have Shiv load me two switchable maps on 880cc injectors (one map for 93 octane, the other for e85). I believe that this is what he accomplished with his 91/e85 tunes...
Shane at DB Performance spent a lot of time working on the driveability factor and part throttle cruise, I wouldn't expect my gas mileage to drop much from what it is unless my foot starts to get a little heavier. 
e85 was interesting while watching the AFRs, I see why everyone says its a lot like tuning on race gas. Some of the first pulls were done at 10.25:1, 10.5 :1, 10.75:1, and then 11:1 all at the same PSI and timing. All of the pulls made similar power, I hope that leaning it out further will show some bigger gains. Shane was taking it in small steps, one small change at a time and going over all the data, he needed to let me go as I was down to a couple gallons of fuel and it was 2 AM on a Wednesday night and I had work in a few hours. I'll be back for the last bit of tuning hopefully soon.

It likes to run a little leaner, just like other race fuels. The other big thing I noticed is it takes a bunch more fuel for start up and this in the main thing to remember, it takes a bunch more fuel in general, so whatever your upgrade path, go with the biggest injectors you're thinking about.
What power numbers at what boost levels and what size injectors at what duty cycles?
