E-85 tuned, stranded for 500 miles with only gas stations
Get a switch and get it done correctly. I have dirven around with 25 gallons extra in the car. Im not really to worried about the car spontaneously combusting. Im just adicted to E85. i can run pump gas but why would I?
Yes, you can drive on pump gas w/ the E85 tune, but you will max out the fuel trims and likely throw a CEL. My suggestion would be to put in some 93 when you're down to a few gallons of E85 to ease in the fuel trims before going straight 93. This will help avoid the start/idle issues with the trims at 0.
And yes, use 93 and not 87/89. Using 87 will only make the chance of knock higher than 93. Also, if you have a manual controller, turn down the boost for the trip back.
Also, whoever suggested putting 10 gallons of E85 in the trunk should consider that 10 gallons will only get him about 150 miles and likely get him really high on the way from the fumes.

If your getting high from fumes maybe you should try to put the lid on the gas can properly. Maybe get some decent fuel jugs. You wont have the fumes, even if its in your back seat you wont notice it...
Guys I decided to go ahead and get a second tune for pump 93. Going to get a tactronix cable and ECU flash so I can switch maps when needed.
Thanks for answering my theoretical question

Are you seriously averaging 15 MPG on the highway?
