Hi all, ive got a slightly moded l67 monte carlo 3.8 SC, i recently found out that there is a gas station that sells e85 nearby. I was wondering what sort of tunes i would have to do to the car for it to handle e85. Its like a dollar cheaper a gallon and id love to save some cash. heres another question, how much of a pain is it to switch back to regular gas, can i just run it to almost empy fill up and reflash?
