DPF Delete Tuners

Improved performance & power with tuners

DPF delete tuners in this collection recalibrate the ECM so the engine runs correctly after a DPF, DEF, and EGR delete kit is installed. They disable regen logic, prevent emissions-related error codes, and apply power levels matched to the hardware on the truck.

The catalog covers most modern diesel platforms: Ford Powerstroke 6.7L, Ram Cummins 6.7L, GM Duramax 6.6L (including LMM, LML, L5P), 3.0L EcoDiesel applications, and selected Mercedes Sprinter and Nissan diesel models.

Key advantages of tuning

A proper delete tuner keeps the engine management system in sync with the mechanical DPF delete kit and the real way the truck is used.

• Prevents constant regens and DPF, DEF, and EGR error codes after a DPF delete.
• Adds measured power gains, often in the 40–150 hp range depending on tune.
• Improves throttle response and torque delivery under tow and heavy load.
• Helps fuel economy in steady off-road cruising, often by 1–3 mpg.
• Offers multiple tune levels for tow, daily, and performance driving modes.
• Provides live data, basic logging, and diagnostics through the tuner interface.

A wide range of tuners and configuration files

The tuners collection includes handheld devices, cloud-based platforms, ECM unlock tools, and bench-flash solutions. Each tuner is matched to specific years, engines, and platforms so the calibration works correctly with the chosen kit.

• EZ Lynk Auto Agent 3 – app-based tuner that connects over OBD-II and uses a smartphone for control. Supports custom DPF delete tunes for Ford Powerstroke 6.7L, Ram Cummins 6.7L, GM Duramax 6.6L, and many 3.0L EcoDiesel models through cloud delivery.
• EFI Live AutoCal V3 – handheld EFILive device for GM Duramax and Ram Cummins trucks. Reads and flashes the ECM, stores multiple calibrations, and works with custom delete tunes built for specific engine codes and hardware setups.
• ECMSync Tuner – platform designed for newer Ford 6.7L Powerstroke trucks with locked ECMs. Handles ECM unlock where required, loads DPF and EGR delete calibrations, and supports shift-on-the-fly power levels through the ECMSync interface.
• Mini Maxx V2 Tuner – dash-mounted tuner with on-screen gauges and multiple power modes. Commonly used on Ram Cummins and selected Duramax or Powerstroke applications for DPF/DEF/EGR delete, tow tunes, and performance calibrations.
• Bully Dog BDX Tuner – Wi-Fi handheld tuner for Ford Powerstroke and other gasoline and diesel platforms. Pulls custom delete tunes from the cloud, loads them over OBD-II, and offers data logging and basic gauge functions.
• ECU Unlock Tool – unlock solution for late ECMs, including many L5P Duramax 6.6L units. Prepares the ECU for DPF delete tuning so a separate handheld or bench-flash service can write the final calibration.
• Bench Flash Tuner – bench-flash option for platforms where on-vehicle OBD flashing is limited, such as certain 3.0L EcoDiesel and Mercedes Sprinter 3.0L models. The ECU is removed, flashed on the bench with DPF/EGR delete software, then reinstalled.
• H&S Performance Mini Maxx V1 – earlier generation dashboard tuner still used on many 6.7L Cummins and 6.4L Powerstroke trucks. Provides multiple power files, monitoring, and DPF/DEF/EGR delete support for off-road configurations.
• RaceME Ultra Tuner – Ram Cummins-focused tuner covering many 6.7L model years. Offers several power levels, shift-on-the-fly control, and integrated DPF, DEF, and EGR delete functions tailored to common delete kit layouts.

In addition to the hardware, this collection includes configuration files and calibration packages built for specific engines and years. These tunes remove DPF, DEF, and EGR logic in the ECM, adjust fueling, boost, and rail pressure tables for the selected power level, and prevent emissions-related error codes after a DPF delete kit is installed.
