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.
I've only towed once with mine so far, but pulling a 6% grade at 62mph in 4th, I was at 2800rpm towing 4,000lbs. I wonder why...we both have 3.73's.
There was plenty on tap though...I could have jumped in the passing lane!
