Description
The Burger Tuning JB4 Performance Tuner is the ultimate plug-and-play power upgrade for 2017+ Porsche 718 Cayman & Boxster models. Delivering up to +75whp and +75wtq on a stock setup, the JB4 remaps boost, timing, and fueling for optimal performance, sharper throttle response, and reduced turbo lag — all while retaining factory drivability and safety systems.
Built with full SENT sensor technology and CANbus integration, the JB4 can access and incorporate advanced engine data to deliver precise performance gains while maintaining built-in protections. Boost remains low until proper oil and coolant temps are reached, and power will automatically drop if knock, overheating, or overboost is detected.
E85 ethanol compatibility, multiple map options, and full app-based control allow you to fine-tune your Porsche for street, track, or daily use — with the ability to revert to stock instantly. Installation takes minutes, requires no ECU flash, and is fully reversible for lease or warranty situations.

What is a JB4?
The JB4 is a next-generation plug-and-play piggyback tuner for turbocharged vehicles. Connecting directly to your Porsche’s sensors and ECU via SENT and CANbus, it optimizes boost, fueling, and ignition timing dynamically for maximum performance.
Unlike flash tunes, the JB4 is fully reversible and continues to evolve with free firmware updates and new maps from Burger Motorsports. Trusted for over a decade, the JB4 has become the gold standard for safe, powerful, and flexible performance tuning.
