I get about 9mpg around town and 13 on the highway on E85, (12.5/15 with 93).

That's in boost that you have the gain right? Does it feel any stronger out of boost versus the gas?

Hard to tell, boost comes on at 1500-1800rpm, but the low end feels much stronger. I find myself rolling into the throttle on E85 because stabbing it under 35 spins the tires, whereas on 93 it doesn't as much.

Yep. I believe JoeyG65 pushed near or over 700 with all stock components aside from pump and injectors. He also noted running E85 for 5 years with no ill effects on the non flex fuel system.
