Soon to be running E85.
Do you have to change any rubber or aluminum fuel system parts that don't play well with ethanol? Just curious as I have heard there are some part differences as well as electronic tuning (hence your tune) in cars equipped to run E85.
Since E85 has higher octane than premium, so[/B] with a proper tune[/B] you will get more power, if that is what you are looking for.
