One Tune Pack That Covers Workdays Weekends And Everything Between

If you drive a 2013 Silverado or Sierra 2500HD or 3500HD with the 6.6L LML, you know the truck has more potential than the factory calibration lets on. This DuramaxTuner Five Tune Pack unlocks that potential while keeping your emissions equipment fully intact and 49 state legal. The Sport tune brings serious excitement with gains up to plus 135 rear wheel horsepower and 243 lb ft of torque, yet it is calibrated to maintain OEM levels of reliability. When you just want a strong and smooth daily driver, the Street tune delivers responsive throttle feel and a clean power curve without excessive soot. For towing, you get both Light Tow and Heavy Tow options that add usable torque while managing exhaust gas temperatures through SMART EGT control. Additionally, the factory turbo brake remains fully functional across the calibrations, so you do not lose the features you rely on. It is like having five personalities built into your truck, ready to match whatever the day throws at you.

Advanced Custom Calibration Designed For Power Control And Reliability

This Five Tune Pack is engineered specifically for the 2013 GM 6.6L Duramax LML and requires the SPADE or EFI Live AutoCal V3 device for flashing. Each calibration includes more than 100 changes from stock, carefully developed to improve airflow management, fuel delivery, and torque control strategies. The Sport, Street, Light Tow, and Heavy Tow tunes are built with air fuel ratio limits to help control soot output while delivering measurable horsepower and torque increases. Furthermore, the tow calibrations incorporate SMART EGT control to automatically manage exhaust gas temperatures under load, which is critical when pulling heavy trailers. An Optimized Stock file is also included, offering a near factory calibration that is useful for diagnostics or when someone else is driving the truck. The tuning retains factory turbo brake functionality and works seamlessly with recommended TCM tuning to improve shift timing, torque converter lockup strategy, and clutch holding capacity. With an included EFILive license and support for multiple VIN slots through the AutoCal V3 platform, this package provides a flexible and professional level solution for LML owners who want controlled, emissions compliant performance.
