The 6.7 CTD with pickup tune for different Transmission offerings:
385 hp and 865 ft-lbs with the Aisin automatic
370 hp and 800 ft-lbs with the 68RFE automatic
350 hp and 660 ft-lbs with the G56 manual
Chassis cab tunes are lower to allow for longer duty cycles.
The 2011 was 350hp/650tq.
2011.5 and 2012 were 350hp/800tq.
2013 were as Bedlam stated above, except the highest was 385hp/850tq. They bumped the tq to 865 in 2015.
