I don't sell my programming here. I do know that the fuel sipper calibration will do nothing for you mileage-wise at highway speeds, cruise control or not. The best calibrations for economy will be either the 65 or 80 HP Daily Driver tunes.
As for towing, you may want to stick with a 40 HP heavy towing tune and possibly the 65 HP towing tune for lighter loads.
The 100 HP performance program should run really well. The main thing to remember is that the transmission is at it's most vulnerable state during shifts (primarily the 1-2 shift) so going easy on the truck until you hit 25-30 MPH is advisable.
