Why Choose the 2019–2020 Dodge Ram 6.7L Diesel Delete Kit from SPELAB?
If you're running a 2019 or 2021 Dodge Ram 6.7L Diesel—especially for towing, daily work, or long-haul operation—you’ve likely noticed the impact of emissions systems over time. While modern emission controls are better than previous generations, they can still lead to performance limitations, added maintenance, and long-term reliability concerns.
That’s why SPELAB offers this all-in-one 2019 Dodge Ram 6.7L Diesel delete kit (also compatible with 2020 models), combining everything needed to remove restrictive emissions components and unleash the engine’s full potential.
Technical Comparison｜Stock vs. SPELAB Dodge Ram 6.7L Diesel Delete Kit Performance
| Feature |
Stock Emissions System |
SPELAB Dodge Ram 6.7L Diesel Delete Kit |
| Intake Cleanliness |
EGR recirculates exhaust gases, leading to heavy carbon buildup in intake |
Clean, dry air enters the engine — no more sludge or carbon deposits |
| DPF Regeneration Frequency |
Regenerates every ~250–450 miles depending on conditions; urban driving causes failures |
DPF fully removed — no more regen cycles, better consistency |
| DEF Consumption |
Consumes 13–15 gallons every 3,000–4,000 miles |
DEF system deleted — zero DEF usage |
| Cooling System Load |
EGR coolant increases system temps by 5–10°F |
Reduced cooling load after EGR removal — better temp stability |
| Fuel Economy |
Averages 12–14 MPG highway; 9 MPG towing |
Gains of 3–6 MPG reported (16–21 MPG average post-delete with tuning) |
| CP4 Pump Risk |
High-pressure CP4 pump used in 2019–2020 — known for failures |
Lower internal pressure and stress after delete, reducing CP4 failure risk |
| Check Engine Light (CEL) |
Common CEL triggers from minor EGR/DPF faults |
CEL codes removed via tuning — no warning lights post-delete |
| Use Case |
Street-legal and emissions compliant |
For off-road, race, and non-highway applications only |
Note:
2019–2020 Dodge Ram 6.7L Diesel models were equipped with a high-risk CP4 injection pump and second-gen emissions systems. The SPELAB All-in-One Delete Kit was designed to simplify, stabilize, and protect your engine — especially under towing conditions.
Real-World Reasons Owners Are Deleting
-
Better towing performance: Many owners of 2020 Ram 2500s hauling daily (like 16-ft enclosed trailers) find that deleting improves throttle response and reduces strain under load.
-
Improved fuel economy: Some users report fuel mileage gains from 12 MPG up to 16–20 MPG, especially during highway travel and unloaded cruising.
-
Preventing long-term failure: The CP4 fuel pump, used only on 2019–2020 Dodge Ram 6.7L Diesel trucks, has a reputation for failure. Deleting reduces system stress and helps mitigate turbo and injector issues associated with exhaust heat and contamination.
-
No more DEF headaches: A full delete means no more DEF refills, fewer DPF regens, and significantly less downtime caused by emissions-related warning lights.
What Makes the SPELAB Kit Stand Out?
-
Complete package: Includes the Mini Maxx V2 tuner, race pipe, and EGR delete kit—no guesswork, no piecing together parts.
-
Tuning built for reliability: Designed to disable all emission-related codes while maintaining drivability and safe engine parameters.
-
DIY-friendly setup: Simple plug-and-play installation with supported PCM software (note: 2018+ trucks must have PCM part numbers that begin with a number).
Is It Legal?
This kit is intended for off-road, race, or agricultural use only. Federal law prohibits the removal of emissions equipment on vehicles driven on public roads in the U.S. Always check local and federal regulations before installing.
FAQ
Q1: Can I delete the DPF/DEF/EGR systems on my 2019 or 2020 Ram 6.7L diesel?
A1: Yes. The SPELAB All-in-One Delete Kit is fully compatible with 2019–2020 trucks and includes a Mini Maxx V2 tuner that supports complete emissions removal.
How do I know if my PCM is compatible with the tuner?
A2: Open the hood and check your PCM part number. If it starts with a number (e.g., “6836...”), it's compatible. If it starts with a letter, contact SPELAB support for further assistance.
Q3: Will the Check Engine Light (CEL) stay on after deletion?
A3: No. The included tuning software disables all emissions-related DTCs and CEL warnings.
Q4: Can I delete DPF and DEF but leave the EGR in place?
A4: Technically yes, but not recommended. EGR left active can still introduce soot into your intake. For full performance and reliability, we recommend removing all three systems together.
Q5: Does the delete help reduce wear on the CP4 pump?
A5: Absolutely. Removing the restrictive emissions systems lowers backpressure and thermal stress, improving the longevity of your turbo, injectors, and CP4 pump.
Q6: Can I leave the EGR hardware in place but disable it?
A6: Yes. Some users opt for a “stealth delete” — the hardware stays for visual compliance, but the function is disabled via tuning.
Q7: How difficult is the installation?
A7: Moderate. Many users DIY the install with basic tools, while others prefer a diesel shop. The kit includes everything needed for plug-and-play installation — no cutting or welding required.
