Show original supplier description
The Burger Motorsports JB4 is an advanced tuning system engineered for the 2022 and newer Toyota Tundra models equipped with the 3.4L V6 Twin Turbo or Hybrid Twin Turbo engines. This system delivers significant power gains, rated up to 60 wheel horsepower (75 crank horsepower) on stock vehicles using pump gas, with even greater increases possible when combined with other modifications or E85 fuel blends. Installation is straightforward due to its plug-and-play harness, and the JB4 is fully reversible. The system features multiple on-the-fly map switching capabilities directly from the dash, boost limiting by gear to enhance traction, built-in data logging for up to 40 engine parameters, and the ability to read and delete fault codes. It seamlessly integrates with all driving modes and does not impact fuel economy during normal operation, requiring 91 octane or higher for optimal performance gains. This JB4 tuner is compatible with the free JB4 PRO mobile app, which allows for wireless connection via Bluetooth to iOS or Android devices. The app provides features for recording and analyzing vehicle data, changing performance maps, and updating firmware with free new versions. The app offers an intuitive interface and advanced log analysis tools. Optional accessories include a front active spoiler delete module to prevent error codes when removing the spoiler and MAP sensor bypass extensions to simplify installation.
