I thought about this, and if I was running actual E85%, then my injectors would be maxed out, but based on estimates, I'll probably just be running E30 or E40. E85 needs to flow about 30% more fuel, so E40 would be about half that and need to flow about 15% more fuel.
One thing I find interesting is that according to a website, blends of fuel with 20%-30% ethanol will get the same gas mileage as fuel with no ethanol.
