TBSIMMONS,
It sounds like it would be worht your whle to take a trip to the dealer. It also sounds like you have a Job 1 that has never been reflashed. Mine did the regen with every hookup until my Job 1 450 reflash in August. This reflash stopped regen during idle (hookups, etc,), and also added messages to Job 1 dash (drive to clean, cleaning, etc). It helped mileage in my 4.30 rear end 450, but understand it did not help the 250/350's with 3.73 rears as much. I think that reflash was available in late June and also believe that that one is not the same one that was out in late October that killed many transmission control modules (tcm's) in the process of reflashing. The reflash that killed all those tcm's has been suspended by Ford. There is no word as to how long it might be before a newer flash will be available, but there still may be one that is newer than the one you have that can save you some grief.
The August reflash also helped with power/boost on the hills. I suspect what now happens during regen when system encounters driver's inputs (pedal etc) "I want more power!*!!" situations, such as going up hills with a load or accelerating onto the highway, is (my belief) that the regen cycle stops, lets you get your power,then starts the regen cycle all over again. So if the system estimated the need to drive 10 miles t current powere settings to clean the system, you drive 8, then stomp on it for more power, system will let you have it (it would not before the reflash) but once back into lower power demand situation, will start the 10 miles of regen all over again, and if interrupted, again and again until it gets the 10 miles in one interrupted shot.
Job 1's might get better mileage if the dash had capability of saying "I am in regen for "X" more miles/minutes, don't accelerate sharply if you want to improve your mileage."
