They love it. There is a drop in MPG when using E85 vs. straight gasoline and a huge increase in HP. I notice no drop in MPG when using "oxygenated" gas vs. "100% gasoline" .

No fuel pump replacement yet...
Have you tried lean burn with E85? You don't even need a different oxygen sensor. Just program the firmware to lean out the mixture at constant throttle and periodically switch back to stoichiometric in order to check the ratio with the oxygen sensor.
