Eco Boost Owners - Anyone using a Tow Tune?
Anyone using a tow tune from a company like 5-Star? If so, does it make a difference? Are you using 87 or 91 octane?

Can't imagine why I'd want to use other than the chip Ford put in there. Climbs 7% grades in fourth gear at posted speed limits and at 1800 RPM stock. This with 10,000 lb. against it's 11,300 lb. rating.
