Description
The Burger Tuning JB4 Tuner for Porsche Macan S, GTS, Turbo Facelift, E3 Cayenne, and Panamera delivers a simple plug-and-play power upgrade without ECU flashing. Designed for the latest Porsche platforms, it features full SENT sensor technology and CANbus integration for precise, safe, and reliable tuning.
The JB4 remaps boost, timing, and fueling to optimize performance, reduce turbo lag, and provide on-the-fly map switching via the optional JB4 Mobile app. Built-in safety systems monitor oil temperature, coolant temperature, AFR, and knock to automatically adjust boost when necessary. Ethanol fuel support allows for E85 mixture tuning, and Revision 2 now includes an integrated boost control connection for higher power applications—no extra module required.
Installation is fully reversible, leaves no ECU footprint, and retains factory smoothness and drivability.
