Looking for feed back on people using E85. Mainly if there are issues with anything on the fuel system that it is not prepared to run alcohol and gas mileage. I understand the great performance increase it gives you. As it is equal to 105oct and no carbon build up. Plus it is forgiving on the air/fuel ratio you run vs if it was gas.
Also I live in Wisconsin so I, like many other states, get 3 blends of this thru out the year. E70(winter), E74(fall/spring), E79(summer). Wondering what tune it comes with when you order it because knowing this will greatly effect the a/f ratio. Plus I assume its mandatory to run a wideband?
Thanks in advance for your input.
