Do you ever hear the fan engage? Most likely the water pump. Plastic impeller has spun on its shaft

yes the fan comes on, ok but what is the difference between pulling hills at 70 stock and 70 with the program? if the impeller has spun i would think it would over heat all the time pulling hard

Running a tune will cause the motor to run hotter when pulling a load, as more fuel, boost, and timing are being introduced to the motor. Most high power custom tunes tell you not to tow or haul anything when running such tunes, as the motor can heat up really fast - especially the EGTs. Tow tunes are designed for towing and usually keep EGTs in check, but even they are rated for a given load.

Is the "Engine Overtemp" alarm coming on? What are the ECTs and EOTs at which you think you are overheating? Failing head gaskets can also cause rapid ECT increases under load, as cylinder temps and pressures get introduced into the cooling system.

Exactly. Sometimes a tune can bring to light problems you didnt even know you had

What SCT tune are you running when you pull the trailer?

How much coolant are you having to put in afterwards?

If you are not venting it out of the coolant recovery cap and you are not leaking anywhere its going somewhere.......

The dirty truth about programmers is: like stated above they can make small problems more noticeable. Tuners advance timing and increase cylinder pressure by several means boost is one.
It could be a head gasket problem, very slight issue with stock cylinder pressures. Crank up cylinder pressure and the leak will increase.
Best way to rule this out is by installing a 30 psi gauge into the cooling system. Normal pressures are around 10 psi + or- 3lbs. Any spikes in pressure under a heavy acceleration is a sure sign of combustion gases entering cooling system.

I hope this is not your issue, but you would be wise to investigate it.
