| The tow mode on the edge is adjusting timing, fule, etc. for power and the tow/haul on your tranny ups line preasure for less slipage while towing a load. You dont really need the tow haul mode unless your towing heavy. As for the towing mode on the edge its works well to keep mpg up and egts down while towing and its tranny friendly for slipage. Hope this helps. |
