2019-Present 6.7 Cummins Performance Upgrades & Delete Kits

Unlocking 5th Gen Potential: Reliability Meets Raw Power

The 5th Gen Cummins (2019-2024) is a highly integrated machine. Upgrading it requires a strategic approach to software and hardware to avoid the common "Service DEF" and "Limp Mode" traps. Our 6.7 Cummins mods focus on the most critical components to ensure your truck runs cooler, stronger, and longer.

1. Emissions & Exhaust (Reliability & Power)

Improving exhaust flow is the fastest way to lower engine stress. The factory EGR (Exhaust Gas Recirculation) Delete Kit is a necessity for the 5th Gen because it prevents hot, soot-filled exhaust from re-entering the intake manifold, which otherwise causes carbon buildup and higher operating temperatures.

Pair this with a DPF (Diesel Particulate Filter) Delete Pipe to remove the massive restriction in your exhaust stream. This eliminates soot-trapping and "regeneration" cycles, allowing your turbo to spool faster and significantly improving MPG.

To finish the build, a Cummins Muffler Delete reduces backpressure or noise levels, giving your 2019 Ram a deep, aggressive exhaust note without the restrictive factory baffles.

2. Tuning & Electronics (Optimizing the 5th Gen Brain)

The Tuner (Programmer) is the "brain" of your performance build. When you remove hardware like the DPF or EGR on a 2022+ Cummins, the ECU must be recalibrated to prevent error codes. Beyond managing deletes, our tuners optimize fuel timing and boost levels to unlock the truck's true horsepower.

After the hardware is removed, protect your investment with a Tuner Harness Plug Kit for 6.7 Cummins 2019-2024. These weather-proof, heavy-duty plugs seal the factory electrical connectors left hanging under the truck, preventing water, mud, and corrosion from causing electrical shorts in your 2019-2024 Ram 2500/3500.

3. Cooling & Engine Vitality (Thermal Management)

Thermal stability is critical for the CGI (Compacted Graphite Iron) block. The 6.7 Cummins Coolant Bypass is specifically vital for the 6.7L Cummins because the rear cylinders—especially #6—suffer from stagnant coolant flow and extreme heat soak. This kit creates a secondary flow path, ensuring even temperature distribution across the cylinder head and preventing the dreaded blown head gasket.

For 2019+ 6.7 L Cummins performance parts, managing this "hotspot" is the best long-term reliability mod you can perform.

Expert Tech Tip: 2022+ ECU SecuritySince 2022, Ram has utilized enhanced security gateways. Our 2022-2024 6.7 Cummins performance kits include the necessary bypass hardware to ensure your delete tunes for 6.7 Cummins can be flashed safely via the OBD port, protecting your 5th Gen’s sensitive electronics.

Frequently Asked Questions: 2019-2024 6.7 Cummins Solutions

Q: Is it worth deleting a 6.7 Cummins?

A: Yes, deleting a 6.7 Cummins is worth it as it offers significant performance gains and fuel savings, especially for off-road use, where better airflow and power are highly beneficial.

Q: How long will a deleted 6.7 Cummins last?

A: A deleted 6.7 Cummins can last significantly longer, with reduced strain on the engine components, potentially reaching over 500k miles with proper maintenance and care.

Q: Does EGR delete cause the check engine light?

A: EGR delete will not trigger the check engine light when using the right tuning tools, such as the Mini Maxx tuner for the 6.7 Cummins, ensuring the system remains in optimal performance.

Q: Can you delete a 6.7 Cummins without a tuner?

A: No, deleting a 6.7 Cummins without a tuner is not recommended, as proper tuning is essential to prevent issues such as check engine light activation, poor performance, and engine damage.

Q: Why is a Coolant Bypass Kit so important for the 2019+ Cummins?

A: On the 2019-Present 6.7L Cummins, the cooling system layout can leave the rear cylinders prone to hotspots. A Coolant Bypass Kit ensures that the back of the cylinder head receives consistent flow, which is the best insurance against warped heads and gasket failures in high-performance or heavy-towing rigs.

Q: Will a delete kit stop my 2020 Ram from going into 'Regen' mode?

A: Yes. By installing a 2020 Ram 3500 delete kit and a DPF delete pipe, you remove the filter that traps soot. When paired with the correct 6.7 Cummins tuner, the truck will no longer initiate regeneration cycles, saving you fuel and reducing engine strain.

Q: How does a Tuner Harness Plug Kit protect my 2022 Ram?

A: After an EGR or DPF delete, your factory plugs are left dangling. Under-truck environments are harsh; our Tuner Harness Plug Kit seals these open connections, preventing "phantom" electrical codes and shorts caused by water or salt intrusion in your 2022 Cummins wiring.

Q: Can I use 2018 parts on my 2019 5th Gen Cummins?

A: No. The 2019+ models feature a different chassis, engine block (CGI), and ECU architecture. You must use 2019-2024 specific 6.7 Cummins aftermarket parts to ensure proper fitment, especially for 6.7 intake horns and exhaust hangers.

Q: What kind of HP gains can I expect on a 2024 Ram with a full delete?

A: With a full 2024 Ram 6.7 delete kit and performance tuning, most High Output (HO) models see gains of 120-150+ HP and a significant improvement in throttle response and fuel economy.

Q: How much horsepower will a tuner add to my 2020 Ram 3500?

A: Depending on the setting, a 2020 Cummins tuner combined with a full delete can add between 100 and 150+ horsepower while significantly increasing low-end torque for better towing performance.

Q: Is it legal to use these delete kits on the street?

A: These kits are designed for off-road, racing, or agricultural use only. It is important to check your local and federal regulations regarding emissions equipment on 2019-Present 6.7 Cummins engine upgrades.
