Features:
If you’re tired of your truck feeling sluggish with a trailer behind it, the Light Tow Tune from DuramaxTuner.com is a game-changer. Built specifically for the 2011 GM Silverado or Sierra 2500HD and 3500HD with the 6.6L Duramax LML, this tune gives you the added muscle you need without going overboard. It offers just the right balance between daily drivability and towing performance, especially for loads under 8,000 lbs. You’ll notice quicker throttle response, smoother shifts, and more useable power when you need it most. Whether you're hauling a small boat for the weekend or running job-site gear around town, this tune makes your truck feel like it should have from the factory. It’s a great option if you want added confidence without sacrificing emissions compliance or overloading your drivetrain. Plus, it includes EFI Live AutoCal v3 hardware to make tuning and diagnostics a breeze. From power to peace of mind, this package is built for hardworking drivers who still enjoy the ride.
This Light Tow Tune includes more than 100 calibration changes from stock to safely enhance performance, throttle control, and drivability. It delivers an additional 55 rear-wheel horsepower and 99 ft-lbs of torque, which helps get your trailer moving without straining the truck. The SMART EGT control actively manages exhaust temps, while built-in air-fuel ratio limits help reduce soot, making it cleaner and more reliable than box programmers. Designed specifically for towing under 8,000 lbs, the tune retains the full functionality of your factory turbo brake and supports smoother low-speed maneuvering. Revised pedal sensitivity and a flattened power curve ensure a more responsive and predictable driving experience in all conditions. This tune is ideal for daily-driven work trucks, service vehicles, or anyone needing reliable towing without the stress of added heat or wear. Combined with EFI Live AutoCal v3 hardware, it also offers data logging, troubleshooting tools, and seamless tune updates for long-term use.
