I thought the same, also I thought maybe he gave me something else perhaps with lead in it and maybe that was why?? They have a 20' container with multiple 50 gallon tanks in it from which he draws the fuel into a smaller bottle then puts it in my car. Maybe he pulled from the wrong one, although I'm not sure why the lead would hurt either. Or perhaps the oxygen in the fuel messed with the dme's AFR targeting? I don't know I figured what you did, at worst it wouldn't do anything maybe I just sucked at driving or something. Makes me want to dyno on the same day running super low with 93 then put some race fuel in and see what it does.
