As far as why our trucks have torque management in the first place, it has more to do with the manufacturer's not having to pay warranty then saving your driveline because all this torque the engine is putting out. The more consumers want these longer warranties, the more the manufacturers are going to stack the odd in their favor in making sure things will last in that warranty period so they do not have to pay. Why do you think torque management is so bad in Ram and GM products who up until recently had the longest warranty while it was not so bad in Ford's? Ram and GM are going to make sure that whatever it is that they warranty for a long time will last in that time frame even from the "idiot" behind the wheel.
Although, what most think is torque management is actually the pedal lag or dead pedal with the DBW system which ALL manufacturers are affected by. Some more than others. Most people think that whatever they do with the pedal will instantly cause the engine to do as well. It does not work that way with drive by wire systems. You may mash the pedal 50% expecting to get 50% of the engines output, but the ECM will only tell the engine to produce say 30% output. Not only that, but the DBW pedal is not instant either. You make give it 50% pedal, but it won't send the signal to the ECM for 50% pedal until a few seconds later because it slowly ramps up to tell the ECM 50% pedal is pushed.
