Inside the 1,000 lb-ft 6.7L Cummins
As I said before, most of the changes were made to keep it clean(emissions wise) and cool at stock power levels while mated to emissions equipment. Although, there is no doubt Cummins is sandbagging ...

As these pickups approach or are in the range of Class 8 power specs they clearly are not built that heavy. So something has to give. I don't think this is a Ford, Ram or Gm specific issue but rather one all have to deal with and how they chose and to what degree they insert nannies. There certainly is a need to keep guys from twisting driveshafts and causing the kind of damage you see on big trucks when too much go pedal is added. My ZL1 has 5 different traction control settings that limit wheel spin and engine torque, you can also kill all nannies. Maybe these pickups end up with something similar. The point I want to make was that the specs sheets on all three of these trucks is over the top. Power is not an issue on any of them, but how the power is allowed to be used is what is most important in my view. Having 1200 pound feet of torque but keeping it hamstrung so that you can seldom get at all of it doesn't really help except in advertisements.
