Five Power Levels That Let Your LML Do It All

If you drive a 2011 Silverado or Sierra 2500HD or 3500HD with the 6.6L LML, you already know the truck has untapped potential. This 50 State Legal FIVE Tune Pack gives you the freedom to choose exactly how that power is delivered without removing any emissions equipment. From the adrenaline packed Sport tune with gains up to plus 135 rear wheel horsepower to the smooth and refined Street tune, you can tailor the truck to your mood or workload. When it is time to hook up a trailer, the Light Tow and Heavy Tow calibrations provide controlled torque and built in SMART EGT management to keep temperatures in check. Additionally, the Optimized Stock file is perfect for troubleshooting or when someone else needs to drive the truck. The result is a setup that makes your Duramax feel stronger, cleaner, and more responsive in every situation. It is like having five different trucks in one, all while staying fully emissions compliant in all 50 states.

Advanced Multi Tune Calibration With Included AutoCal V3 Hardware

This FIVE Tune Pack is engineered specifically for the 2011 6.6L Duramax LML and carries E.O. D-845 approval for 50 state legal use. Each calibration features more than 100 changes from stock, carefully refining fuel delivery, torque management, throttle response, and shift strategy to enhance performance and drivability. The Sport, Street, Light Tow, and Heavy Tow tunes are built with air fuel ratio limits to reduce soot output while maintaining strong, usable power. Furthermore, tow specific files incorporate SMART EGT control to automatically manage exhaust gas temperatures under load. The included EFI Live AutoCal V3 provides simple handheld flashing capability, data logging, and the flexibility to receive tune updates when needed. An EFILive license is included for one vehicle, and transmission tuning is strongly recommended to optimize torque converter lockup and clutch holding capacity. When properly supported, this package delivers a comprehensive and emissions compliant tuning solution for LML owners who want flexibility without compromise.
