your not alone, ive felt the same thing with mine.

With a United e85 tune, when i use the eflex, it uses more fuel, slight drop off in power in the top end but overall runs perfect, slight sooting up of the tips.
When using the Untied fuel, there is a bit more power, exhaust is clean as and you can smell the ethanol content a little more. Fuel usage is reduced.
