Here's an idea, did your "friend" push the Tow/Haul button which disables the MDS? I assume no offset still think it's MDS. There was a TSB for torque converter programming which fixed the hesitation problem.
Anyways, back to fuel mileage comparisons and not "My friends broken non-Ford" like every other thread in this forum...
I don't know if he tried the tow haul mode or not. He used to be a big Jeep enthusiast until this happened. I looked on a Jeep forum a months ago and saw people were still having the problem. His inlaws have on that also does it.
