In theory, E85 is better for the hub (assuming you're not using kickdown). Sure more power, but you're not redlining it; to get the most out of an E85 tune, you're shifting at 6300-6500. When do hubs spin/slip? Usually on kickdown when the car overrevs or on a 6mt money shift.
Unless you have upgraded turbos or PI, S55 turbos run out of breath around 6500, thus, no need to push to redline.
My take anyways. I did the hub.
