I thought E85 had more HP (advanced timing?) but less MPG...that was the experience my brother had with his flex fuel Silverado and I had with a flex fuel F150...I recall them even being advertised with more horsepower when using E85...anyway, they seemed more peppy to me but lost 2-4 MPGs

They do have more power. I can never remember the specifics, but, in the GMT900s, it's something like +11HP and +13TQ. This is on actual E85. You'll lose about 27% fuel economy.
My local E85 pumps are actually around E65 consistently. So, about 23.5% lower ethanol than E85. As such, I "only" lose about 21% of my E0-E10 fuel economy. I can't say the extra power is anything I can feel so much. But, there's too much else goin on with mine that it's irrelevant when comparing stock on E0 to stock on E85.
