Ford Motor Company announced through an official press release on August 3rd, 2010 that the 2011 6.7L Power Stroke diesel's power output is being increased from 390 hp and 735 lb-ft to a whopping 400 hp @ 2,800 rpm and 800 lb-ft @ 1,600 rpm. The 10 horsepower and 65 lb-ft increase will be issued on all new trucks coming off the assembly line.
Furthermore, current owners may receive the performance increase via a PCM software update free of charge at their local dealership. Dealerships will also be performing the upgrade on all the 6.7L Power Stroke powered trucks in their inventory.
Ford's upgrade for the 6.7L Power Stroke earns the 2011 Super Duty best in class horsepower and torque, a title they previously held until GM upgraded the performance of its 6.6L Duramax. The Duramax boasts 397 hp and 765 lb-ft of torque, while the 6.7L Cummins currently peaks at 350 hp and 650 lb-ft of torque.
The bold move to provide free updates to current owners indicates Ford's confidence in the 6.7L Power Stroke, and is sure to make already happy customers that much more satisfied.
