What does a 6.7 Cummins Delete Kit do?
A 6.7 Cummins Delete Kit is designed to enhance your truck’s performance by removing restrictive emissions systems. Depending on the kit you choose, it can remove one or more of the following components. For example, a basic 6.7 Cummins delete kit may only remove the EGR system, but most “full” or “all-in-one” delete kits remove multiple systems, including EGR, DPF, and DEF.
EGR (Exhaust Gas Recirculation): The EGR system recirculates exhaust gases back into the engine to reduce emissions. Removing it lowers intake temperatures, reduces soot buildup, and improves engine efficiency.
DPF (Diesel Particulate Filter): The DPF traps soot and particulate matter from the exhaust. By removing it, you allow for better exhaust flow, which reduces backpressure and boosts engine power.
DEF (Diesel Exhaust Fluid): The DEF system reduces NOx emissions by injecting urea into the exhaust. Removing this system eliminates the need for DEF, improving fuel efficiency and lowering maintenance costs.
By removing these components, a delete kit helps your engine run more smoothly, efficiently, and with fewer maintenance issues.
FAQ
Q1: What Parts Does the Spetuner 6.7 Cummins Delete Kit Remove?
A1: The Spetuner All‑in‑One Ram Cummins Delete Kit removes the following factory emissions systems:
- DPF (Diesel Particulate Filter)
- DEF (Diesel Exhaust Fluid System)
- EGR (Exhaust Gas Recirculation)
- ECM Tuning Support (if needed)
By eliminating these components, the kit restores engine power and reliability for Ram trucks equipped with the 6.7L Cummins diesel engine.
Q2: Do I need a tuner after EGR deleting on the 6.7 Cummins?
A2: Yes, a tuner is required after EGR delete to prevent error codes and check-engine lights. While some kits claim to work without a tuner, the engine’s ECU will detect the missing emissions components, leading to diagnostic trouble codes (DTCs). To avoid this, we recommend pairing your delete kit with a tuner designed for delete applications, such as the H&S Mini Maxx or EFI Live.
Q3: What are the key components of a 6.7 Cummins delete kit?
A3: The comprehensive delete kit for 6.7 Cummins should include the following components:
- Race pipe or full exhaust to replace the DPF and CAT system
- EGR delete hardware (block-off plates, coolant reroute, and fittings)
- DEF delete plug or simulator
- Tuner, such as EZ Lynk or EFI Live, loaded with custom tunes
- Optional muffler for reducing exhaust noise
Q4: What delete kits are recommended for a Ram 2500?
A4: The best delete kits for a Ram 2500 include comprehensive bundles that remove the DPF, DEF, and EGR systems, often paired with a tuner like EZ Lynk or EFI Live. The best option depends on your truck’s year and performance goals.
Q5: Can I delete a 6.7 Cummins without removing the EGR?
A5: Yes, you can delete the 6.7 Cummins without removing the EGR system, but for optimal performance, an EGR delete is always recommended.
Q6: What is a full delete on Cummins?
A6: A full delete removes all factory-installed emissions control systems, including the DPF, EGR, and DEF systems. This process involves installing high-flow exhaust and intake components and reprogramming the truck's ECU to eliminate emissions-related software.
Q7: How much does a delete kit cost?
A7: The cost of a delete kit varies depending on the components included. On average, expect to pay:
- EGR delete kit: $400–$700
- DPF delete kit: $700–$1,200
- DEF delete kit: $200–$400
- CCV deletes: $40-$250
- Tuner: $600-3000
Q8: Which Ram models are compatible with the All-In-One Delete Kit?
A8: The All-In-One Cummins Delete Kit is compatible with Ram 2500, Ram 3500, and Cab & Chassis trucks from 2007 to 2022. Ensure compatibility based on your truck’s year, trim, and intended use.
