Description
The Burger Tuning JB4 Group 13 is a powerful, fully adjustable plug-and-play performance tuner designed for Volkswagen and Audi 2.0TSI engines, including the MK6 GTI, Golf R, Jetta GLI, CC, Tiguan, and Audi S3 8P.
With up to +60hp gains on a stock vehicle and even more with bolt-ons, higher octane, or ethanol blends, the JB4 offers performance, safety, and versatility far beyond a basic chip tune. Thanks to CANbus OBDII integration, it directly monitors boost, AFR, fuel trims, ignition timing, and engine knock, adjusting in real time for optimal performance and protection.
It comes preloaded with up to 8 custom maps for pump gas, E85 mixtures, race fuels, and valet mode, all accessible via the optional JB4 Mobile or JB4PRO Bluetooth app. Installation takes minutes, is fully reversible, and requires no ECU flash, making it compatible with locked ECUs.

What is a JB4?
The JB4 is a next-generation piggyback tuner for turbocharged engines. It installs between your car’s sensors and ECU to fine-tune boost, fueling, and ignition timing for maximum safe power gains.
Unlike basic piggybacks, the JB4 features CANbus integration, fuel and spark control, E85 mapping, boost-by-gear, data logging, fault code reading, and ongoing free firmware updates. It’s completely reversible, making it the safest and most versatile performance upgrade available for VW and Audi 2.0TSI models.
