I just paid of my 2014 Ram 3500. The truck has a 6.7 H.O with 84k miles, single Axle 4x4. Im adding a 4" lift and 35's. I need advice on getting the engine to run better/cleaner. Not to worried about big HP numbers, just want to run better. I've got around 2K to spend. Thinking EGR delete, DPF delete, CCV oil catch and a tune. Is the the best way to go? Are certain brands that are more compatible than others? What are you guys running on your trucks and what would you do different?
