Eco Boost Owners - Anyone using a Tow Tune?

I have not personally taken the plunge, as I'm still under warranty. But if I do, it will be with 5star. You can like their facebook page and check out their EB shop trucks, and the stuff they pull with. It has been a common theme that they may not make the most power, but their shifting strategies are supposed to be awesome when pulling. They keep all factory safeguards in place, such as torque management.

It has also been said that mpg will increase 1-2mpg with pretty much any tune out there.

I don't particularly dislike my shifting strategies, but then again, I've never been in a tuned EB.
