Description
The Burger Tuning JB4 for 2017+ Porsche Carrera, S, T, and GTS is the most advanced plug-and-play tuning solution for the 991.2 generation. With power gains of up to 40 horsepower and 60 lb-ft of torque to the wheels, it delivers sharper throttle response, reduced turbo lag, and increased top-end power—all without an ECU flash.
The JB4 uses SENT sensor technology to properly tune Porsche’s latest platforms while full CANbus integration ensures precise boost, timing, and fueling adjustments using real-time engine data. Built-in safety systems manage boost based on coolant and oil temps, prevent knock damage, and drop to low boost if the engine runs lean or overheats.
It also features ethanol (E85) fuel control, allowing for advanced flex-fuel tuning. Using the optional JB4 Mobile or JB4PRO Bluetooth adapters, you can change maps on the fly, log performance data, clear codes, and install free firmware updates as Burger Tuning releases them. Installation is fast, discreet, and fully reversible without leaving a trace.
