I'm envious of those who have easy access to 93 and E85. All I've got is 91, and the nearest E85 station is three hours away. With a JB4 (with flex fuel wires) on map1, my timing always looks a lot better with a few gallons of ethanol mixed in. I'd run MS109 daily if I could afford it!

The car will adjust the fuel trims for the enthanol, and will inherently run more timing and possibly more boost enabled by the higher octane. The octane is the critical number regarding power (and overall knock prevention in general), the ethanol content is irrelevant so long as you're not maxing out the stock fuel system.

I'm running E85 with a JB4 w/FF wires. Pushes 18psi boost easy day. Blew my stock charge pipe last weekend, lol. Cobb Chare pipe going this week.

Caution, if you run less than 91 octane for a prolonged period of time, you will get a Cel, with an engine running lean code. After that I pretty much just put in 93 octane. I was mixing 93, and 89 to get 91, but sometimes, was just below 91.
