You could
MAYBE run 2.5 - 3 gal of E85 to a full tank of 91 to get your octane up. A lot of people including my self have done this or are still doing this to run the 93 cobb maps without having 93 available. I assume it would work the same way with this. Just have to watch your fuel trims to make sure your not running to much E85 if so you have some adjusting to do either in the fuel scalar or at the pump.
