towing rpm

What rpm does Cummins say is a safe and best range to run the 6.7 at while towing? I know that my old 24 valve was best in the 2100 to 2450 range on the highway as far as the torque and fuel curve went. the 6.7 seems to run good at 2200 to 2400 also. does Cummins recomend this? they said to drive the 24 valve all day at 2400 rpm and it wouldn't hurt it. I haven't seen a fuel curve chart from Cummins on this engine like the ones available for all the other motors.
