It wakes the truck up with an extra 55 RWHP and 99 ft-lbs of torque, giving you more usable power when you need to move quickly, merge into traffic, or pull a trailer without strain. It’s not just about horsepower, though, this tune smooths out throttle response, improves low-speed control, and gives your truck a much more refined feel behind the wheel. Whether you’re towing a small camper, utility trailer, or just hauling gear for work, this tune helps your truck feel stronger without overdoing it. It keeps the factory turbo brake fully functional and works seamlessly with the emissions system, making it a safe and 50-state legal upgrade. Plus, it’s ideal for seasonal towers, tradesmen, and weekend adventurers who rely on their truck for both work and play. If you want better drivability with towing support built in, this tune delivers exactly what you’re looking for.

Purpose Built Calibration For Light Duty Towing Needs

DuramaxTuner’s Light Tow Tune for the 2018 RAM 2500 and 3500 6.7L Cummins is a fully emissions intact, 50-state legal calibration designed for reliable power and improved drivability when towing under 8,000 pounds. With over 100 adjustments from stock, this tune modifies throttle sensitivity, torque delivery, fuel mapping, and air-fuel ratio controls to give your truck a smooth and responsive feel across all driving scenarios. The tune includes SMART EGT control, which actively monitors and manages exhaust temperatures to keep your engine safe under load. It also features air-fuel ratio limits that reduce soot production without compromising performance. This calibration is especially useful for drivers running factory hardware but still looking for a boost in torque, better throttle feel, and more control while maneuvering with a trailer. It retains all OEM safety functions like turbo braking and can be further enhanced with optional TCM tuning to fix shift points and improve transmission behavior. Ideal for daily drivers, occasional towers, and work trucks, this tune brings a refined, reliable edge to your truck’s performance.
