Find the torque ratings for the transmission, transfer case and rear axle and you will find your max engine torque number...
My understanding is that the 140 in the 6R140 indicates the torque value that was designed into the transmission. In 2013 H&S fed fuel to an otherwise stock Powerstoke. (not sure about the turbo) The transmission began to slip at over 1600 lb ft of torque. I think in 2015 Ford beefed up the 6R140 slightly.
edit:
the 140 signifies 1400 ftlbs
