So, on to my 4th revision of my E85 tune, and I have to say I am 100% happy with the choice to install E85.

the ability to go back and forth from E85 to 91 is great. The tune automatically adjusts based on the percentage of e85/alcohol in the tank.

That being said, to maximize both the gas tune and E85 tune, you should be filling up with either when you are on E/Gas light is on. That is going to take some getting used to for me, as I try to never go under half a tank.

the power gains are astronomical. I have no dyno numbers yet. but, just driving the car, and letting a few others drive the car who have only driven it on the 91 tune....they were floored. As am I.


A+ in my book!
