I'm in the process of converting my car to e85 now. I should be finished re-plumbing my fuel system with 1/2" line tonight (I had 3/8"). First TNT is in a few weeks, I'll post my results if you like. I'm guessing it might take a few TNT sessions to get the bugs worked out. Our cars run almost the same on gas so hopfully I'll have some helpful info for ya soon :smile:. Everyone I have talked to has picked up a little or at least run the same, and most have said that their consistency has improved...I guess I'll see for myself shortly.
