Just throwing that out there. There is more to this than just the octane rating of the fuel.

Thanks for throwing that list up there, shotgun!

Cody - why do you say that? I don't think I understand at all.

He's got a "flex-fuel" truck, which has been designed to burn the E85 crap and, like shotgun says, it should adjust the A/F mixture for the proper stoich (9.85) as long as that fuel is being burned.

Are you saying that the canned performance tune will try to hold the A/F ratio at or near 14.64 regardless of the fuel used? If that's the case, I understand and yes - I would not use ANY of the canned tunes with the fake gas. But, as you can tell, I didn't think it would work this way. Can you clarify?

Thanks in advance my friend. Hope you're staying warm up in the frigid north country!
