Default 2011 6.7 Fuel millage? Delete? Programmer?

About a year ago I bought a 2011 6.7 Quad Cab Long box and was wondering what fuel millage I should be expecting? This is my first 6.7 and I seem to be getting around 14-15 with no load and 10-12 pulling. I have a Edge Programmer, Cold air intake and removed the muffler and none of that seem to make a difference on the MPH as I kind of suspected but it was easy bolt on stuff and enjoy the power and sound. I have owned some 5.9s and they all got around 20 or more with one getting 30+ mpg with a bunch of after market stuff done to it, so I'm just curious if this is normal for the 6.7?

I have been told by some locals that I need to Delete it and throw out my Edge. I'm not really excited about that as I do love the Edge. Thoughts?

Don't throw the edge away - run it over so no one else is stuck with it. Get EFI tuning- best hands down.

My 09 6.7 I get about 18 empty mix driving around town/interstate- this is overhead. I have not calculated by hand as I haven't had the truck long enough.

Also I am intrigued to know what mountain you were coasting down with a wind at your back to get 30+ mpg with your 5.9 😂
