Is your fan clutch working alright? a/c condenser, intercooler, radiator fins clean? Coolant level correct. What setting are you running the programmer on?

I was running in the tow mode on my edge and had the tranny in tow also The first two cars I hauled I didnt have the edge could it be over fueling my truck? I will check the raidator and clutch fan but if something was wrong with them wouldnt it overheat all the time?

not necessarily.

i have been running for the better part of a year with out any fan at all and it doesn't over heat (except once). granted it will run a little on the hot side when driving below 30 mph for extended time. i dont tow much so i have been able to get away with it like this

towing puts a much greater demand on the cooling system. when you add a programmer and increase the fuel the cooling system now has to dissipate the extra heat generated and can overheat easier.

i would, as suggested above, check the cooling system and maybe even a coolant flush and replace the thermostats.
