Description
The Burger Tuning JB4 Tuner for the 2025+ RAM 1500 3.0L I6 Hurricane Twin Turbo delivers massive gains of up to +104 wheel horsepower on a completely stock truck running pump gas. Designed for both Standard Output (SO) and High Output (HO) variants, the JB4 instantly transforms your RAM into a harder-accelerating, more responsive powerhouse—without the risks of ECU flashing.
The JB4 uses a Plug & Play harness and CANbus OBDII connection to integrate directly with the factory ECU, actively monitoring and adjusting over 40 critical engine parameters like boost pressure, timing, air/fuel ratio, knock feedback, and more. This allows it to deliver smooth, reliable power gains while adding advanced safety protections.
With 8 preloaded maps for different fuels, bolt-on modifications, and E85 blends, plus boost-by-gear control for better launches, the JB4 is equally at home on the street or track. Additional features include in-dash map switching, built-in code reading, progressive water/methanol integration, and free firmware updates for ongoing improvements.
Pair your JB4 with the JB4 Mobile app or JB4PRO for wireless logging, map changes, and real-time performance monitoring from your smartphone.
