Maybe I was spoiled with the C16 results but there was a HUGE difference between the two. I won't run anything other than C16 on top of 93 when making glory pulls.

Like Greg said, I wouldn't do that if I were you. Besides, you are still running E85 all the time, right? That stuff seems to have quite a high ceiling for power capability.

nah, im not going to. The only thoughts I had was to use a fuel that would show up on the knock sensor to help find what the engine likes in general. Then when going back to the better fuel you'd be plenty safe. Since e85 doesn't really show knock on our setups you just have busted parts before you know it.
