The Juice module is an add-on Engine Control Module for the Duramax engine that offers additional features not available with the factory setup. Since it is an add-on ECM, it uses all the factory data and then enhances the factory settings to optimize your truck’s performance.

The Juice features engine temperature monitoring and power increase from the Juice module as engine reaches operating temperature. With four selectable power levels using the gear shifter and tow/haul button, the Juice module offers a large power increase over stock throughout the RPR range, but the power is more noticeable in the midrange RPM’s. This greatly improves driveability and towing performance. Transmission downshifting is greatly reduced, especially while passing or towing.

The Juice also regulates power delivery and timing based on engine temperature. This means that while the engine temperature is below 160 degrees Fahrenheit, no additional fueling or timing is delivered. Over 160 degrees, the module begins modifying timing and delivering fuel at 50% of the calculated additional fuel, and the percentage increases as the engine temperature increases, until at full engine temperature the Juice delivers 100% of the calculated additional fuel.

The Juice alone provides the following power gains with:
Level 1: 40 Horsepower - 150 Foot Pounds of Torque
Level 2: 60 Horsepower - 180 Foot Pounds of Torque
Level 3: 75 Horsepower - 200 Foot Pounds of Torque
Level 4: 90 Horsepower - 250 Foot Pounds of Torque
