I've been running E85 with the level 3 tune and just filled up today. I don't think level 2 to will work with E85, last time I tried the check engine light came on and the truck went into limp home mode, or it was just running rough, not sure why, probably tripped the knock sender.
I guess I will run this tank out and switch to regular gas and then to level 2 sense it works fine with 87.Tell then Ill take it easy, lol.
