Product Details

The Edge Products 30203 EZ Module is a proven plug-and-play performance upgrade designed for 2003-2004 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This module delivers EGT-safe horsepower and torque gains that improve towing performance, throttle response, and everyday driving.

Performance Gains:

  • Level 1: +25 HP / +50 ft-lbs torque
  • Level 2: +45 HP / +75 ft-lbs torque
  • Level 3: +65 HP / +120 ft-lbs torque

Key Features:

  • Installation takes only minutes with simple factory connections—no cutting, splicing, or complicated tuning required
  • Level 1 produces fuel economy gains of 5-10%
  • Improved throttle response eliminates turbo lag while added torque reduces downshifting when towing up steep grades
  • Designed to keep exhaust gas temperatures in check while unlocking true engine capability
  • Connects directly to the vehicle's MAP sensor and data link to adjust fueling and timing parameters
  • Includes in-cab switch for easy power level adjustment

This module is 50-state legal with CARB Executive Order D-541-18, making it emissions-compliant for use nationwide. Specifically designed for the legendary 24-valve common-rail 5.9L Cummins, the EZ Tuner is ideal for daily drivers, work trucks, and towing applications where reliable power and safe operation are essential.
