The DEF delete tuner for RAM 6.7 Cummins requires vehicle-specific calibration. Pickup and Cab & Chassis trucks use different configurations, and transmission tuning availability depends on the installed gearbox.
Components
- EZ Lynk Auto Agent 3 - Wireless OBD-II interface used for engine programming, live monitoring, and diagnostic communication.
- Custom ECM Tune Files - Vehicle-specific calibrations supplied electronically through the EZ Lynk platform for the selected engine and hardware configuration.
- SOTF Tuning - Included functionality providing five selectable engine power levels without a complete ECM reflash between settings.
- Tuning Support Package - Provides access to the assigned tuning service, with four-week or unlimited support options depending on the purchased package.
- Optional TCM Tuning - Transmission calibration for supported configurations when selected or included in the purchased package.
- 2018 Bypass Cable - Additional programming connection hardware required for compatible 2018 vehicles.
The EZ Lynk Auto Agent application is available as a free download for compatible smartphones. Exhaust components, EGR removal parts, and other mechanical hardware are not included with this standalone tuner.
Tuning & Performance
The DEF delete tuner 6.7 Cummins 2013-2018 communicates with the factory ECM through the vehicle's OBD-II diagnostic connection. Custom calibrations adjust engine-management strategies to match the hardware installed on the truck.
For legally permitted off-road applications, the appropriate tune coordinates engine operation with modifications to the restrictive DPF, DEF/SCR, and EGR systems. Removing emissions components without corresponding ECM programming can trigger fault codes, warning messages, and reduced-power operation. Installing a calibration for removed components while retaining incompatible factory hardware can also cause operating problems.
Properly matched tuning may provide:
- Improved throttle response and acceleration.
- Increased horsepower and torque at higher settings.
- Elimination of DPF regeneration cycles after the associated hardware has been removed.
- More consistent engine performance under varying loads.
- Adjusted fuel delivery and boost management.

The 2013-2018 RAM 6.7 Cummins DEF delete tuner includes five SOTF power settings for compatible applications. These are nominal increases over factory output, not guaranteed dyno results.
Optional TCM tuning addresses transmission calibration separately from ECM horsepower levels. Actual performance, fuel efficiency, and shift behavior depend on the vehicle's condition, transmission, installed hardware, and selected configuration.
Installation
The EZ Lynk tuner for 6.7 Cummins uses smartphone-guided programming, allowing experienced owners to complete the electronic installation without a conventional handheld programmer.
- Download the EZ Lynk Auto Agent application to a compatible smartphone.
- Connect the device to the vehicle's OBD-II port using the required connection hardware.
- Establish the wireless connection and register the device.
- Provide the VIN, model year, body style, transmission, drivetrain, tire size, and existing modifications.
- Connect with the assigned tuning technician and access the custom calibration through the EZ Lynk platform.
- Maintain stable battery voltage and follow the application instructions to complete ECM programming.
For 2018 Ram trucks, the required bypass connection must be available before programming. Transmission tuning, when purchased, follows the applicable configuration-specific procedure.
The electronic setup and flashing process can generally be completed in under an hour once the correct files are available. Mechanical installation requires additional time and appropriate tools.
Professional assistance is recommended for complex configurations. DEFDelete provides product-related technical support and installation guidance.
