I originally planned on waiting until my warranty was up to delete my 2016 Cummins. I have made it 7,500 miles and my DEF system has thrown codes on two separate occasions. Codes were not active when I got to the dealer but they said it was from being so cold and not getting proper flow. If I'm going to get a check engine light every time it's -25 in Minnesota then I may as well just say eff it and just get it over with now.

Looking for a mild tune with a physical delete of the EGR and all that jazz. Pro or con from going Turbo back for exhaust versus CAT back on the exhaust? Looks like RaceMe with a tune from Double R is a popular suggestion in here?

saw somebody said something about it made their turbo spool on a cold start on a RaceMe box tune but I think it does that from the factory as it mine does it on cold starts below -10 (or that's when I noticed it at least)

Anybody want to hold my hand for a minute and give me a suggestion or should I just call the guys at Double R tomorrow?
