Sounds quieter, and starts amazingly. IDK, its kind of strange. Haven't pushed it much past 4k yet, but can't really tell that much of a power difference to be completely honest...

I just filled up on E85 again yesterday.. this morning it didn't take 2 cranks to fire up, but it felt like it was choking slightly on the first crank before firing up. Once it gets cranked however, my car drives much smoother & with a little more oomph on E85 than it does with 93 octane. Not a huge difference, but I can definitely feel it.
I don't really care much what degradation, if any, is happening... I'm not going back to 93 anymore, startup issues or not. My car likes the corn juice!

You probably just need to get your E85 tune tweaked a bit if it's not running better than your 93 tune.
