If you use E85 gas, Bill will adjust your tune so that it performs the best it can with that stuff in the tank. In my opinion, unless E85 is VERY much cheaper than real gas, you are better off not using it. It has a much lower energy content than low alcohol blends and will not give you good fuel economy.
The tow tune is customized for the kind of towing YOU do, not a range of tow weights from 500-8000#. Again, if you use E85 gasohol when you tow, the tune should be adjusted for it to get the maximum benefit.
