I have to check what rear I have, but my economy is horrible right now on 35"s and running E85 only. Average reads 10 mpg, with highway and some city combined. It was reading 13-14 when I bought it, but pretty sure they were running regular 87 on it. Might switch back and see what happens.

E85 is horrible for mileage. Right now however the price spread is almost 90 cents. So I may start burning while the price spread is pretty good. I ran it one tank and averaged about 12. But, I've been pulling my trailer a lot lately and only been averaging about 14-16 anyway on regular 87 so we'll see how bad the mileage hit is on E85.

Check your manual, JDM - I'm not sure you should be running E85 in a 3.5 EB.
On second glance, maybe you have the normally aspirated 3.5, which I think is OK.

I've been thinking though, pretty sure my speedo is a bit off due to the 35"s. Reads 30 when I'm doing like 33 according to speed traps. That would make my fuel economy read wrong too right? Since the ecm thinks I travel less per rotation than I actually am, right? I turned off trailer sway control, reading 10.5 now. Ran like 5 full tanks of E85 so far, might switch back to 87 after this next tank. Price difference is good around here, almost a dollar. Thats why I went with e85 to see what the power difference would be like.
