I’ve been thinking about doing a 6.7 Cummins DPF delete, but I’m trying to understand the real pros and cons before making a decision. I know the truck was originally designed to run with DEF and the emissions system, and the cost of DEF itself isn’t really my concern.
What I’m really interested in is a deeper explanation of the benefits and downsides of doing a 6.7 Cummins DPF delete—things like reliability, performance, long-term engine health, and anything else I should consider.
I’d appreciate hearing from anyone who has experience with it or has researched it in detail.
Thanks!
