The way it apears to me is if I wanted max hp then yes I would have to add a buch more fuel and timing, however since I am just leaving everything the same for MPG purposes and simplicity it is fine. I pulled a couple plugs after running most of the tank out and no sighns of metal flakeing or burning or anything abnormal. Some guys told me it would be so lean it would cause detonation even with 100+ octane but it was the oposite, the ocational one or two knocks going up a steep hill were totally gone all together, no knocking whatsoever. It will probably be a couple more tanks of it before I pull the heads for the compression bump and inspection.

I am thinking of jetting up the secondaries a bunch for the e-85 after I do the switch so I can take advantage of the extra fuel and oxygen content. That way I can have my MPG and HP too!
