I have a 91 and E85 map. Have only used my 91 map twice since I was tuned on E85. If I do run 91, I'll run down the 91 till its almost empty, I then fill up on E85 and switch to my e85 map but keep the boost down at 18psi(91 map boost level). Ill run at least 3 tanks of E85 before I even think of turning up the boost to 21psi and doing and hard pulls. Havent had any issues and car still runs strong.
I only average about 30-40 miles more per tank on 91 compared to E85. On 91 I'd go about week and half before filling up, E85 I usually fill up weekly

Why not do a setup like the FLI one found here ?

I know that when I went to e85 I had so much 91 in my lines, injectors, and tank Ed thought I had something wrong with my car. Took about 3 tanks of e85 till it ran good and now it's smooth as butter 
I also would not change between 91 and e85 cause its very picky gas and likes to be 100% e85

I pumped 6 gallons of E85 on Friday in my tank. I'm tuned by ED on 91... The car feels a bit more responsive and sounds normal. Normally i dont put this much, I usually pump 2 gallons or so every other month to clean things out but I totally dazed out on the pump....I'd like to see a tune chime in and hear what they have to say

It may not sound like a whole lotta extra miles, but when I was on 91, I'd average around 315-330 miles per tank...that was also when I didn't have as many mods...HAHA.
But still, one of the main reasons I'm thinking about also getting a 91 map is because there are more regular gas stations around as opposed to E85. If I need to go on a long drive/road trip, 91 is readily available versus E85.
Hmm......
