Heavy Tow Tune Only L5P (2020-2023)

Light Tow Tune Only L5P (2020-2023)

Our custom Light Tow tune is the safest way for those who tow recreational vehicles and other smaller payloads with your 2020, 2021, 2022 or 2023 Chevy Silverado, or GMC Sierra. What's light? Under 8,000 lbs. Our fine-tuned calibrations expertly optimize for power, torque, smoke, vehicle reliability, and better fuel consumption. Using the Light Tow tune with a payload over 8,000 lbs could have slightly higher EGTs if the situation is strenuous for the truck (pulling a huge trailer up a steep mountain pass in the middle of the desert during summer).
