2022-2024 Cummins Delete Tuning Kit

It’s a better DIY option than the rest.

Here is my personal experience comparing the Diesel Patriots and Diesel Dudes kits on my 2024 Ram 3500 6.7 Cummins. I originally installed the Diesel Patriots kit with its non-HP tune. The truck ran, but the tune felt very basic and restricted. It lacked throttle response, barely reached 20 PSI of boost, and occasionally started rough after sitting. The factory intake heater also no longer worked unless I wired it to a separate switch. I later switched to the Diesel Dudes kit with the replacement ECM and RaceME Ultra. Even on the stock-power setting, the truck is noticeably more responsive, reaches over 30 PSI of boost, starts better, and the factory intake heater works correctly. I’m also seeing approximately 3–4 MPG better at 70–75 MPH and 2–4 MPG better while towing the same car trailer and side-by-side. An experienced custom tuner could probably produce even better results, but I installed everything myself and these are the results I experienced. I’m not against either company or telling anyone how to spend their money. Yes, I spent a lot figuring out what worked, but it’s my truck and my money. You live and learn. For anyone comparing the two kits, I would choose the Diesel Dudes ECM-swap setup again

★★★★★ Outstanding Product Bundle — Even Better Customer Support

I recently purchased an equipment bundle from The Diesel Dudes for my 2024 Ram 6.7 Cummins, and I could not be more impressed—not only with the products themselves, but especially with the exceptional level of customer service I received both before and after the sale. Mike and Jami have been excellent throughout the entire process. They were knowledgeable, responsive, and genuinely invested in making sure everything went the way it should. During the installation, I encountered a small technical issue with the tuner. Technical issues can happen with any combination of sophisticated electronics and performance equipment; what matters is how a company responds when they do. This is where The Diesel Dudes truly distinguished themselves. Jami responded within the next business hour and personally phoned me to work through the issue. There was no runaround, no waiting days for an email response, and no feeling that once the sale was complete I was on my own. She was sincerely helpful, knowledgeable, and focused on getting the issue resolved. That level of service carries particular weight with me because, prior to 2007, I owned a diesel performance company myself. I have experience on both sides of this industry, and I know firsthand how dramatically the quality and responsiveness of post-sale support can vary. Some vendors can take days—or even a week—to respond when a customer needs technical assistance. My experience with The Diesel Dudes was exactly the opposite. Any company can look great when everything goes perfectly. The true measure of a business is what happens after the sale, when an unexpected issue arises and the customer actually needs help. That is when you find out what kind of company you are really dealing with. Jami, Mike, and the rest of the Dudes and Dudettes absolutely did it right by me. They didn’t simply sell me a bundle of parts and electronics—they stood behind what they sold and supported me when I needed them. That kind of responsiveness builds trust, and that trust has earned my future business. I will absolutely be back the next time I need something for my truck. Excellent products, exceptional post-sale support, and people who genuinely stand behind what they sell. The Diesel Dudes have earned my highest recommendation.
