What’s Included

Component Description
EZ Lynk Auto Agent 3 Vehicle interface for ECU programming, live monitoring, and diagnostics. A compatible smartphone or tablet serves as the display through the Auto Agent app.
OBD-II connection cable Connects the device to your truck for communication and programming. These RAM applications also require the appropriate security gateway bypass cable.
VIN-specific tuning — with a tuning package Provides custom ECU files matched to your vehicle and selected configuration. A hardware-only purchase requires a separate tuning package.
Installation instructions Guide you through device connection, account setup, profile download, and calibration installation.

A compatible SOTF switch is required for supported multi-level tuning. Compare the selected package options before ordering: bypass cables, switches, and transmission tuning must match your application. Exhaust parts and EGR removal components are purchased separately.

Vehicle Compatibility

  • Years: 2019, 2020, and 2021.
  • Make: RAM, also commonly searched as Dodge RAM.
  • Engine: 6.7L Cummins turbo diesel.
  • Pickup models: RAM 2500 and 3500.
  • Cab & Chassis: Supported applications require dedicated calibrations and separate power settings.
  • Transmission: Specify your installed transmission, including 68RFE or AISIN where applicable.
  • Connection: The appropriate security gateway bypass cable is required.
  • Application: Off-road and competition use only.

Correct fitment depends on the vehicle configuration. Provide your VIN, model year, transmission, 2WD/4WD configuration, tire size, turbo details, and fuel-system modifications so the selected profile fits your truck.

How work?

The 2019, 2020, 2021 RAM 6.7 Cummins tuner for DPF delete installs a custom calibration through the vehicle’s diagnostic connection. This profile adjusts engine control settings and the software functions associated with DPF, EGR, and DEF equipment for the intended off-road configuration. You connect your mobile device to the Auto Agent, download the assigned profile, and follow the programming prompts. Physical removal of factory emissions components requires separate hardware; the tuning interface handles the software changes.

Features

An EZ Link tuner 6.7 Cummins setup combines wireless mobile operation with real-time gauges and diagnostic access. Custom profiles are calibrated for the vehicle details supplied when ordering. Supported pickup configurations offer SOTF switching with the matching file and physical switch. Four-week and unlimited support options provide different periods of access to tuning files and updates.

Tuning & Settings

Pickup and Cab & Chassis applications use different tuning configurations. Horsepower figures below describe advertised increases over factory output, rather than guaranteed measured results.

Pickup power settings

Setting Advertised horsepower increase
Level 1 +30 HP
Level 2 +60 HP
Level 3 +90 HP
Level 4 +120 HP
Level 5 +150 HP

Supported pickup SOTF configurations allow level changes without a complete ECU reflash. Choose the setting according to vehicle condition, drivetrain capability, and operating load.

Transmission tuning

Transmission Tuning option
68RFE Optional TCM calibration with compatible tuning packages.
AISIN Separate transmission calibration for supported configurations.
Engine tuning without TCM Engine calibration only; transmission software remains unchanged.

TCM tuning can adjust transmission control settings to complement engine performance. It is a separate option and does not automatically change the five engine power levels listed above.

Cab & Chassis settings

Model year Available single-tune targets
2019–2020 0 / +50 / +75 / +100 HP
2021 0 / +50 / +100 HP

For C&C applications, these are alternative targets for a selected single calibration. They do not represent the pickup five-level SOTF package.

Tuning can improve throttle response and optimize power delivery. Fuel economy depends on driving conditions and load; increased horsepower does not increase factory towing ratings or replace maintenance needed for reliability.

Key Benefits

Vehicle-specific tuning. Custom profiles account for your VIN and reported modifications.

Mobile programming. Install supported calibrations using your phone and the Auto Agent app.

Live monitoring. View supported engine parameters to understand how your truck operates.

Pickup SOTF capability. Change supported power levels with the correct calibration and switch.

Optional transmission calibration. Add compatible TCM tuning when your drivetrain configuration supports it.

Installation Information

Setting up an EZ Link tuner for 6.7 Cummins 2019-2021 requires a compatible mobile device, the Auto Agent app, internet access for downloading profiles, and the correct connection cables. Basic hand tools may be needed for the bypass cable and optional switch installation.

Follow the included instructions and maintain stable battery voltage throughout programming. Resolve existing diagnostic problems before tuning, and keep the engine off during flashing as directed. Download the correct file, complete the installation prompts, and follow the supplied sequence before you remove emissions equipment.

FAQ

For owners choosing a tuner for 6.7 Cummins, its useful features include mobile programming, custom profiles, and live monitoring. Pickup SOTF capability and optional transmission tuning provide additional flexibility for a compatible setup.

This DPF delete tuner for 6.7 Cummins provides access to supported diagnostic codes and clearing functions. A recurring warning requires diagnosis; clearing the code alone does not repair a mechanical or electrical fault.

The factory ECU may detect missing equipment and trigger warning messages or reduced-power operation. The software and hardware configuration must match for the intended off-road application.

The pickup configuration described above offers five levels: +30, +60, +90, +120, and +150 HP. Cab & Chassis applications use a separate single tune selected for the model year and vehicle configuration.

Returning to the original calibration requires an available, compatible stock file. Factory emissions hardware must also be restored to match that calibration before operating the vehicle.

Installing a diesel tuner for 6.7 Cummins 2019-2021 involves connection, profile download, and ECU programming. Allow an uninterrupted session and follow the app’s progress; cable installation, file preparation, and shipping are separate from flashing time.
