If you can make your egr come up missing, most all your problems engine wise will be eliminated. If you have to change your third brake light bulbs or cargo lights, might as well put silicone on the old gasket cause it will leak no. So far my 14 has 140k, deleted at 133k before my egr decided to go again. Previous owner had intake and egr done at 109k and it was starting to fail again when I deleted but caught it in time. Diesel tech told me don’t stretch out oil changes past 7-8k, keep an eye on your coolant the first few months.
