6.7 Towing 23.5K

Wow, I decided to push my luck a little today and see if my three month old 6.7 could handle about 23.5K on the hitch. I was a little nervous hitting the road with about 5900 lbs of trailer and 17.5K of mulch but it pulled really well.

I don't think I'd dare to hit any of the 12-15% grades like City Park Road in west Austin but the rolling hills weren't bad. This is my first truck with an auto (68RFE). I'd be interested to hear from fellow gear heads what mods are needed to handle a Smarty in the top HP settings. I'm assuming a torque converter and valve body type mods are a given. I'd like to eventually have a Smarty on this truck for towing but don't want to have to do a ton of mods like input/output shafts. My 02' towed great with my Smarty on #9.

I used to my 02' NV5600 that only needed a SB Con ofe ( OK two Con ofe's) to handle an extra 800 ft lbs of torque and 350 HP. My 02' would handle 17-18K on the steep grades but I don't think it would have handled this 23.5K load.
