They increased to 6.7 so the engine would operate under less load to better meet emissions. On a 6.7 you get some great stuff... Exhaust recirculated through your intake system. Exhaust = Heat. So much for cool clean air entering your engine. Wait!... Now you get a cooler for your EGR... WooHooo! sorry! but a cooler = more garbage under hood... and theres more! The good ole DPF along with a regeneration cycle. = more garbage. Dont forget to use your low ash oil! Oop's... you didnt stick some 2 cycle oil in your tank did you? The new ULSD is junk without additives. Im sticking with the 5.9.
