here is a copy and paste from the tow settings thread in the Phoenix forum
DJ,

It breaks down like this:

* 25hp - Over 20,000 GCWR (all terrain)
* 40hp - 16,000 to 20,000 GCWR (all terrain)
* 65hp - 12,000 to 16,000 GCWR (all terrain), 16,000 to 20,000 GCWR (flat terrain)
* 80hp - 8,000 to 12,000 GCWR (all terrain), 12,000 to 16,000 GCWR (flat terrain)
* 100hp - 8,000 to 12,000 GCWR (flat terrain)
* 120hp - Not Recommended
* 140hp - Not Recommended


Keep in mind that files designated as "Tow" are designed specifically for the needs of towing (shift strategies, pressures, lockup, fuel curves, injection timing) while "Performance" programs are handled quite a bit differently.

Hope that helps.
