Description
The Burger Tuning JB4 for the Porsche 992 Turbo & Turbo S is the most advanced and power-packed plug-and-play tuner available for the latest generation 911 Turbo. With power gains of up to 120 horsepower and 140 lb-ft of torque to the wheels, this tuner transforms your 992 into a supercar killer—all without needing to flash your ECU.
The JB4 seamlessly integrates with your factory DME through high-precision engine bay connections and SENT + CANbus technology. It works in conjunction with the factory ECU to precisely remap boost pressure, ignition timing, and fuel delivery, dramatically increasing performance while maintaining drivability and safety.
It features intelligent safety systems, including temperature-based boost limits, knock response, and boost reduction during lean or overheating conditions. The JB4 also includes ethanol (E85) fuel control, unlocking more power for flex-fuel setups.
Via the optional JB4 Mobile or new JB4PRO Bluetooth adapters, you can switch between multiple preloaded maps, log engine data, clear fault codes, and update firmware as new versions and features are released. Installation is fast and discreet, with no permanent changes—fully removable without a trace.

What is a JB4?
The JB4 is the gold standard in plug-and-play performance tuning for turbocharged platforms. Unlike flash tunes that overwrite your ECU, the JB4 installs between your vehicle's sensors and ECU to dynamically enhance performance using real-time data, CANbus integration, and custom mapping.
With support for boost-by-gear, E85/flex-fuel tuning, and app-based map switching, the JB4 offers unmatched control and safety. Free updates, custom maps, and full reversibility make it the top choice for Porsche performance enthusiasts.
