good point but standard gasoline is already E10, but who knows if they actually put exactly 10%. I would expect manufacturers to account for that in their tunes, and if I were to tune for E85 I would try to be a little rich to be safe.
BTW I ran straight E85 in my 84 volvo 242 turbo on 10lbs of boost without a problem. that was only to pass emissions which worked:bigok:
