I have the same truck. Before you go to do the delete you might try something else. Clean the EGR valve, the EGR cooler and replace the DPF filter. Look it up on YouTube. It's not that hard to do if you know how to operate a wrench. Where they say to buy the MOPAR brand of cleaner, ignore them. $30 plus for a liter. Go to a local auto parts store and buy a gallon of purple power for $6.99.

EGR Cleaning kit with filter Under $130
When you go to the site click the tab "Install and Tech Information" Very good instructions for the job.
Many do not realize this is standard maintenance on these trucks.
