Pulling the trigger on a delete

I have a 2016 6.7 Cummins I am getting ready to delete. I was looking for a video to walk me through the deleting process. I’m planning on running an mm3 tuner with double r diesel tunes. Thanks for all your help!

Just deleted my 2016 this past weekend. Pretty straight forward. Egr instructions were kinda vague but easy to figure out if you have basic mechanic skills and there are a lot of videos floating around out there. I am running the mm3 from double r Diesel and I couldn’t be happier! I did the delete myself in the garage. Too easy

The def system is more of a pain than difficult. All of which is relatively easy just time consuming. I know Ray has some good videos as far as the mm3 goes. Just watch videos before you hit it and you’ll be fine. Read threads and pickup tips and tricks there.

That you very much for your help. When you did the delete did you leave the DPF tank in place or did you remove it? And I found a couple good videos finally seems pretty straightforward

I have plans at some point to either throw in a titan tank or horns. Neither of which are a NEED so it sits there. I have used a siphon to empty what I could but it will crystallize if you don’t empty it. Unless you want the cleaner install, I’d empty it and leave it there. I’m in the frozen north and I can only imagine snow boogers would collect there and the salt block would just find more places to attack my truck.

Yes def tank. Sorry for the typo and I will leave my in place then.

Howdy! Just finished mine and went with the DRD MM3 tuner as well. Great tuner and the best customer service you'll find anywhere! The exhaust is pretty straight forward. I followed one person's advice and started in the middle. Huge mistake. If I had to do it again I'd start with the tailpipe and work forward. Heckuva time installing 5" down pipe!! The EGR is not too bad, just lots of stuff to come out and a few nuts/bolts are hard to get to. Be sure to thoroughly tape up all the empty plugs and wire tire them. Ray at DRD also sells plugs to cap them off if you prefer. Here is a video I watched for a little guidance...it helped me quite a bit. Hope it helps you too.
