Power Up Your Tow Rig Without Losing Driveability

If your 2013 Duramax LML is your daily driver and your tow rig, this Light Tow Tune is made for you. It brings just the right blend of extra power and smooth drivability without pushing your truck too hard. Whether you’re hauling a small camper, UTVs, or work equipment under 8,000 lbs, you’ll notice quicker throttle response and more confidence in every shift. The added +55 RWHP and +99 ft-lbs of torque wake the truck up and help you move through traffic or get up to speed on the highway without breaking a sweat. Plus, the revised pedal feel makes low-speed trailer maneuvering way more manageable. This tune is designed to work with your emissions equipment, keeping you 50 state legal without sacrificing performance. It’s also a solid choice if you’re someone who drives their truck to work during the week and pulls toys or tools on the weekends. This is power that shows up when you need it and stays out of the way when you don’t.

Engineered For Light Duty Towing With Built In Safety

This Light Tow Tune is custom-built with more than 100 calibration changes to enhance towing performance while protecting your truck’s critical systems. It’s calibrated to deliver a clean power curve that adds usable power throughout the RPM range, not just at wide-open throttle. Features like SMART EGT Control actively manage exhaust gas temperatures, and built-in air-fuel ratio limits help keep soot production in check. The factory turbo brake remains fully functional, and the tune ensures you can Shift Up, Throttle Back when you need to climb a grade or merge with traffic. It's specifically designed for loads under 8,000 lbs and optimized for both performance and reliability. Backing up trailers or parking with a load is easier too, thanks to improved pedal sensitivity and smoother low-speed response. And because it’s emissions intact, you stay compliant while gaining noticeable improvements in drive quality and power.
