For 2007.5–2010 Duramax 6.6L LMM trucks, the factory DPF and EGR systems can cause exhaust restriction, soot buildup, frequent regeneration, and reduced performance. This DPF/EGR Delete + EFI Live AutoCal V3 All-in-One Kit combines the necessary delete hardware with compatible tuning to match the truck's modified configuration, helping improve exhaust flow, throttle response, and overall performance while avoiding calibration issues associated with removing emissions components without proper tuning.

EFI Live Autocal V3 DPF/EGR Delete All-in-One Kit Key Features

• Complete Delete + Tuning Solution: Combines DPF/EGR delete hardware with an EFI Live AutoCal V3 tuner, providing a matched solution instead of purchasing the components separately. 
• Reduced Exhaust Restriction: Delete exhaust options provide a less restrictive exhaust path, helping improve exhaust flow and airflow compared with the factory emissions configuration.
• Improved Throttle Response & Drivability: Compatible tuning is designed to match the engine calibration to the modified hardware, helping deliver more responsive throttle feel and smoother overall operation.
• Better Performance: Under Load A less restrictive exhaust system combined with appropriate tuning can help the engine operate more efficiently when towing, hauling, or working under demanding conditions. 
• Multiple EFI Live V3 Configurations: Choose between V3 w/ SOTF Switch for selectable tune levels or V3 without SOTF Switch for a standard tuning configuration.
• Off-Road / Competition Applications: Designed for off-road, race, or competition use where permitted by applicable laws and regulations.

EFILive AutoCal V3 DPF/EGR Delete Tuner

Standard vs. SOTF: Choosing the Right EFILive AutoCal V3 Tuner

The standard version offers fixed tuning, requiring manual updates for any changes, making it suitable for users who need a single performance setting. In contrast, the SOTF (Shift on the Fly) version allows real-time switching between multiple tuning modes while driving, providing flexibility for those who need to adjust performance quickly under varying conditions, such as towing or off-roading. 

Key Features of V3

• Precision Tuning: Customize your engine’s performance with precision. The EFI Live AutoCal V3 allows you to fine-tune parameters to maximize horsepower, torque, and fuel efficiency, giving you the ultimate driving experience.
• EFI Live Delete Capability (DPF / EGR / DEF / SCR): Designed for off-road and competition use, the EFI Live platform AutoCal V3 allows a professional tuner to disable the DPF, EGR, DEF, and SCR monitoring logic at the software level through custom calibration files. Once flashed, the ECM no longer looks for signals from these deleted components, so the truck runs without check engine lights or limp mode after the DPF, EGR, and DEF/SCR hardware are removed.
• Advanced User Interface: The AutoCal V3 comes with a larger, more responsive screen and an upgraded interface, making it easier than ever to navigate and adjust your settings.
• Custom Tune Support: Store and switch between multiple custom tuning maps tailored to your specific driving needs—whether it’s for daily driving, towing, or high-performance use.
• Portable Design: Compact and easy to carry, the AutoCal V3 allows for on-the-go tuning. With the ability to store multiple tunes, you can effortlessly switch configurations to match any driving condition.

Important Notice
