Ive read the 6.7 is getting refreshed in many areas...
The updated 2020 Power Stroke includes a new 36,000-psi fuel injection system with all-new injectors that Super Duty Chief Engineer Mike Pruitt says more precisely meter and spray up to eight times per stroke to control noise levels and optimize combustion. The engine features a redesigned electronic-actuated variable-geometry turbocharger for improved pumping efficiency and throttle response. Worth noting is that Ford used a new turbo, new injector nozzles and exhaust improvements to squeeze out 40 more horsepower and 80 more lb. ft. of torque for the 2015 model year, achieving power output of 440 hp / 860 lb. ft. torque. Pruitt says structural enhancements for the 2020 engine increase the strength of the cylinder head, block, connecting rods and bearings to handle the higher cylinder pressure and increased output. New steel pistons provide higher firing pressure capability and less friction for added performance, more horsepower and torque.
