One of the most misconstrued topics in the diesel world is how emissions equipment impacts your truck. Many people believe that deleting your Cummins DPF will enhance your truck’s performance and help solve DPF/EGR failures. Well, the data around these systems has been building up for quite some time. With enhancements of the DPF and EGR engineering, these systems aren’t like they were when they first hit the market in 2007.5. When Cummins moved from the 5.9L engine to the 6.7L the DPF was brand new and as with many first generation parts, failed often.
Now, if you think that simply deleting your DPF is going to gain you 100 HP and 5 MPG, you're going to be surprised by what we have found with real world data. Not to mention, the current state of EPA involvement within the diesel performance community should be on your radar if you are looking for deletes.
