That's what I'm thinking since trims are trending negative. I'll give it some more time to adjust and if it stays rough then I'll just go back to 91.

Also, the gas needle was on the red so I assumed I was about to run out but I put in exactly 11.5 gallons of e85 so there must have been two more of 91 in there.
