I am new to this forum so I am not sure if this has been addressed yet. Is the new low sulfer diesel fuels the cause of poor fuel mileage?
or is it the emissions on the new 6.7? Just trying to understand why these new trucks are getting such poor mileage
Any clarification would be appreciated

I have the new 6.7 and have done the DPF delete kit and blocked the egr too. I have seen no noticeable increase in fuel economy by removing the DPF, which really surprised me to tell the truth. But did see around 2.5 mpg increase when I also blocked the egr. I am running the Juice w/attitude also. I am becoming more and more convinced that a lot of the loss in fuel economy is due to inefficiency in the transmission. hopefully in a few months ATS will have the Torque converter ready for this truck and then we will see how much better it gets.

Unloaded I've seen *** high as 23.2 mpg running 75-80 mph with the ac cranked...that was on a 1300 mile trip from Kansas to Florida. In town I see 16-17s mpg with a good deal at city speeds, and some short highway runs. This truck has always turned good milage since new. My truck is all stock with the exception of a K&N drop-in air filter. I should mention that I have the Aisin tranny.
