96-03 Dodge 4.7/5.2/5.9L Stage 2 Module

The 96-03 Dodge 4.7/5.2/5.9L Stage 2 Module from JET Performance is a tuning solution engineered for second-generation power optimization in Dodge trucks and vans equipped with these displacement engines. Built for mechanics and enthusiasts seeking measurable gains without extensive engine modification, this module addresses the factory ECU's conservative fuel and timing maps. Whether you're running a 4.7L V8 in a Dakota, a 5.2L in a classic Magnum application, or a 5.9L Cummins diesel alternative platform, this Stage 2 calibration unlocks additional horsepower and torque while maintaining street-legal reliability and OEM component compatibility.

The Stage 2 Module operates by reprogramming engine management parameters—primarily ignition timing advance and fuel injection duration—to extract performance from your existing displacement without requiring internal modifications. JET Performance's strategy focuses on maximizing combustion efficiency across the RPM band while respecting knock thresholds and fuel octane ratings. The compact module design (7.6 x 2.4 x 7.6 inches, weighing just 0.37 lbs) plugs directly into the factory ECU harness, making installation a straightforward process for any technician familiar with underhood wiring. This non-invasive approach preserves warranty coverage on unmodified components and allows easy reversion to factory settings if needed.

Ideal for truck owners seeking towing capacity improvements, better throttle response, and fuel economy gains under cruise conditions, the JET Performance Stage 2 Module suits both daily drivers and work vehicles. The module is compatible across 1996–2003 model years, covering a broad range of Dodge Ram 1500/2500/3500 trucks, Durango SUVs, and Dakota pickups. Installation requires no tune-up tools or dyno time—simply locate the ECU beneath the driver's side dashboard, unplug the factory connector, and insert the module. For owners planning further modifications such as exhaust upgrades or cold-air intake systems, this Stage 2 calibration provides a proven foundation that synergizes with popular bolt-on accessories.
