With the Smarty jr for MY 2010 and up, Torque settings is not available, but setting timing to "default" sets it to the highest setting, so your going to have higher EGTs, for towing use Catcher #2, and as for timing? You will have to experiment with timing settings, as not all trucks react exactly the same. I ran the jr on my 2005, best fuel mileage was Catcher 2 (which was oddly the "tow" setting and timing at 2 with torque at 4) Main thing is to try the different settings on or near the same road/wheather conditions for comparison, only way to determine what's going to work best for your truck. I would recommend that Catcher tune #3 not be used for towing, 3 is the "performance tune". Could make things hot, and hard on the tranny.
