Full DPF/DEF/EGR Delete Kit w/ EFI Live AutoCal V3 | Ram 6.7L Cummins | 2010-2021

Ram 6.7 Cummins delete kit with EFI Live AutoCal V3 (2010-2021)

The Ram 6.7 Cummins Delete Kit with EFI Live AutoCal V3 tuner removes the factory DPF, EGR valve, EGR cooler, and applicable DEF/SCR components from supported 2010-2021 Ram pickups. The complete package combines model-year-specific exhaust hardware with custom ECM tuning to stop forced regen cycles, reduce exhaust restriction, and provide calibrated power for daily driving or towing.

What's included in 6.7 Cummins delete kit

• EFI Live AutoCal V3 - The handheld programming device connects to the truck through the factory OBD2 port and installs a custom calibration created for the specific VIN and vehicle configuration. The device also stores supplied tune files and supports diagnostic scanning and calibration updates.

• Vehicle-Specific Custom Tune File - The calibration is prepared from the truck’s VIN, model year, transmission type, tire size, engine modifications, turbocharger setup, and intended use. Supported applications may receive multiple power levels through SOTF or a single fixed tune, depending on model year and configuration.

• SOTF Switch and Calibration - Trucks can switch between supported power settings without reflashing the ECM. The supplied switch controls the available Stock, +30 HP, +60 HP, +90 HP, +120 HP, and +150 HP settings when multi-level tuning is supported.

• Complete EGR Valve and Cooler Removal Kit - The 6.7 Cummins EGR delete kit includes the block-off plates, fittings, hoses, gaskets, and supporting hardware required to remove the factory exhaust gas recirculation valve and cooler. Removing the recirculation hardware reduces soot entering the intake system.

• DPF Delete Pipe or Complete Exhaust System - Buyers can select a direct-fit delete pipe, a 4-inch exhaust, or a 5-inch exhaust system. Each option replaces the factory diesel particulate filter and related restrictive exhaust section.

• DEF/SCR Removal Support - The 2013–2021 configurations include tuning support for the applicable DEF and SCR system. The 2010–2012 Ram trucks did not use the same DEF/SCR layout and therefore receive model-year-specific hardware and programming.

• Installation Hardware - The package includes clamps, fasteners, brackets, seals, and mounting components for the selected exhaust and EGR configuration.

• Installation and Programming Instructions - Detailed instructions explain the hardware removal process, AutoCal connection, tune installation, SOTF setup where supported, and correct programming sequence.

What changes by model year: 2010-2012 vs 2013-2017 vs 2018 vs 2019-2021

Identical across supported 2010-2021 pickups: EFI Live AutoCal V3 programming, vehicle-specific custom tuning, SOTF support, and multiple power levels are available across all four configurations. Exhaust and EGR hardware are supplied according to the selected model year. 

Vehicle compatibility

• Years: 2010–2021

Performance & tuning

The DPF delete tuner provides vehicle-specific engine programming for work use, towing, daily driving, or higher-output applications.

• No forced regens

• Improved throttle response

• Stronger towing response

• Potential fuel economy gains

• Lower EGTs under load

• Reduced exhaust restriction

Gains by power level

Note: Available tuning options may vary based on model year, transmission, and vehicle configuration. Actual horsepower and torque can vary depending on fuel quality, tire size, turbocharger setup, supporting modifications, elevation, and overall mechanical condition. 

Performance summary

The 6.7 Cummins delete kit with tuner changes engine operation after the factory emissions hardware is removed. Custom tuning does not increase the truck’s certified towing capacity or repair pre-existing fuel, turbocharger, transmission, or electrical problems.

Which configuration should you choose?

The selected exhaust, muffler, and tune options determine sound level, installation layout, and calibration flexibility.

A stainless steel exhaust offers corrosion resistance and long service life. A 5-inch system can create a deeper tone, but a larger diameter alone does not guarantee more horsepower than a properly configured 4-inch system.

How the delete kit works on your Ram 6.7 Cummins

The package removes restrictive aftertreatment components and installs ECM programming written for the specific truck.

1. Confirm the model year and transmission type.

2. Remove the DPF and applicable DEF hardware.

3. Install the selected exhaust and EGR components.

4. Flash the custom file with AutoCal V3.

5. Select supported power levels through SOTF.

The custom calibration stops factory monitoring of the removed particulate filter, EGR valve, cooler, and applicable DEF/SCR equipment. Correct tuning also prevents supported regen requests, dashboard warnings, emissions codes, and emissions-related reduced-power operation caused by missing components.

Installation information

The package includes detailed mechanical and programming instructions. A customer with solid mechanical experience and basic computer skills can install the EFI Live Autocal v3 package, although exhaust fasteners, EGR access, and model-year differences can increase installation time.

RECOMMENDED: Battery charger or stable power supply during programming

Stable battery voltage should be maintained while the calibration is being written. An interrupted flash caused by low voltage can prevent the ECM from completing the programming sequence.

Technical specifications

No More Emissions Codes

Correct installation and tuning disable supported emissions codes associated with the removed DPF, DEF/SCR, and EGR systems. The supplied programming does not repair unrelated engine, turbocharger, fuel-system, transmission, wiring, or sensor faults.
