Product Description
EDGE PRODUCTS 21500-3 JUICE WITH ATTITUDE CTS3 – 2001–2004 LB7 DURAMAX
The EDGE PRODUCTS 21500-3 JUICE WITH ATTITUDE CTS3 is one of the most powerful and feature-rich inline diesel tuning systems available for the 2001–2004 LB7 Duramax. This system combines the proven Juice module’s performance gains with the industry-leading Attitude CTS3 touchscreen monitor, giving Duramax owners unmatched control, visibility, and customization. Experience dramatic improvements in throttle response, torque output, towing performance, and driveability—without requiring ECM reflashing.
The Juice module adjusts critical fueling and timing strategies inline, providing multiple power levels that can be switched instantly from the CTS3 screen. The high-definition display allows users to monitor boost, EGT, transmission temperature, injector balance rates, and dozens of additional parameters. Safety defueling settings protect the engine by automatically reducing power if temperatures or boost exceed preset limits. This makes the Juice with Attitude perfect for both towing and performance applications.
