This Tune Makes Towing Feel Effortless Every Time

If you use your truck for both work and weekend towing, the Light Tow Tune with EFI Live AutoCal v3 is the sweet spot you’ve been looking for. It gives your 2011 LML Duramax a noticeable boost in power and torque without sacrificing reliability or comfort. With an extra +55 rear-wheel horsepower and +99 ft-lbs of torque, your truck will feel more responsive and more capable under load. Whether you're hauling a small boat, a couple of ATVs, or a loaded utility trailer, this tune helps you move quicker, smoother, and with less effort. The throttle feels tighter, and low-speed trailer maneuvering becomes much easier, especially when backing up. And because it’s 50 state legal and emissions intact, there’s no guesswork or concern about compliance. It’s a perfect everyday tune for landscapers, laborers, or anyone who tows under 8,000 pounds and just wants their truck to feel more alive.

Designed For Smart Towing Without Sacrificing Driveability

This Light Tow Tune was built for truck owners who demand real-world performance without risking the health of their engine or emissions systems. With over 100 calibration changes from stock, the tune focuses on driveability, safe towing, and throttle refinement. It uses DuramaxTuner’s SMART EGT Control system, which actively monitors and manages exhaust gas temperatures to help protect your engine when towing. Air-fuel ratio limits are programmed right into the calibration to reduce soot, helping extend the life of your emissions components. The tune retains factory turbo brake functionality, so you still get dependable downhill control. It also adjusts pedal sensitivity to improve responsiveness in everyday driving and while trailering. And thanks to EFI Live’s AutoCal v3, flashing your truck is simple, plus you can log and troubleshoot engine data when needed.
