I run blends of E85 in my 01 Blazer 4.3, basically anything up to about E50 in ratio runs AWESOME, acceleration is notably smoother, enough that when my GF borrowed it while it was "drunk" on ethanol she said "your car is way faster than normal, did you do something to it?"

But the engine is unmodified - apart from a high-flow intake tract/filter which serve to increase the "problem" with running E85 in a non-flex-fuel vehicle - a/f ratio. I get about 15% worse fuel efficiency, MPG-wise on a 50/50 blend of E85/straight gas.

I keep wanting to get a FullFlex system but I just don't feel confident enough in that particular company's method - it seems an awful lot like a guess to me.
