I'm also unclear how someone can claim a power improvement from going to E85 without any timing adjustments. Can someone explain how that works? I'm at a loss.

They are mistaken if they believe that under similar conditions they are seeing similar fuel economy (much less an increase) with E85 over E10 or regular petrol.

E85 allows you to change the timing to a range not possible to run on standard gasoline due to knock. Without a tune to take advantage of it, you should not see any difference in power. It's like putting 94 octane in a Prius.
