One Truck That Adapts To Everything You Do

If you use your 2011 Duramax for more than one job, the Five Tune Pack with EZ Lynk AutoAgent 2.0 gives you the flexibility your truck has always been missing. This setup lets you switch between Sport, Street, Light Tow, Heavy Tow, and Optimized Stock tuning, so your truck feels right whether you are towing, commuting, or just enjoying a hard pull on the highway. The Sport and Street tunes bring the excitement back, delivering strong throttle response and serious horsepower that makes the truck feel lighter and more alive. When it is time to hook up a trailer, the Light Tow and Heavy Tow tunes keep power usable and controlled, helping you move weight without stressing the engine. Everything stays emissions intact and fully 50 state legal, so you never have to compromise compliance for performance. Using your smartphone, you can change tunes, monitor data, or clear codes in just minutes. It is the kind of upgrade that makes one truck capable of doing everything better.

Calibrated Power Levels Built Around Control And Reliability

This Five Tune Pack is custom built for the 2011 Silverado and Sierra 2500HD and 3500HD with the 6.6L Duramax LML and includes over 100 calibration changes across each tune. The Sport tune delivers up to 135 rear-wheel horsepower and 243 ft-lbs of torque for maximum acceleration, while the Street tune balances strong gains with smooth daily drivability. Light Tow and Heavy Tow calibrations use SMART EGT control and optimized air-fuel ratios to manage temperatures and reduce soot under load. Factory turbo brake functionality is retained across all towing tunes, maintaining downhill control and confidence. The included EZ Lynk AutoAgent 2.0 plugs into the OBD-II port and allows flashing, diagnostics, and data logging directly from your iOS or Android device. Automatic firmware updates and included tokens make long-term use simple and hassle free. For best results, transmission tuning is recommended to improve shift quality, torque converter lockup, and overall drivability under increased power.
