Good morning all. I have a 2016 6.7 Cummins 4x4 crew cab. My family is getting a little bigger so I need something a little better on fuel. A buddy of mine did a delete on his cummins and sends me pics every now and then that shows he avg. 40mpg and 1050 miles per tank. I'm curious to know what MPGs everyone else is getting after deleting the EGR and DEF. The little that I could find still avg around 22. Thanks in advance.
