Description
Unlock the full potential of your 2025+ Audi B10 S5 or SQ5 with the Burger Motorsports (BMS) JB4 Performance Tuner, the industry's most advanced plug-and-play tuning solution for the 3.0L EA839 turbocharged V6 engine.
Engineered to deliver exceptional performance without permanently modifying your factory ECU, the JB4 provides gains of up to 85 horsepower at the crank (approximately 70 WHP) on an otherwise stock vehicle using premium pump fuel. Additional performance is available when combined with bolt-on modifications, higher-octane fuel, or E85 ethanol blends.
Unlike basic piggyback modules, the JB4 utilizes advanced CANbus integration and real-time engine monitoring to intelligently adjust boost pressure, ignition timing, fuel trims, and other engine parameters while retaining the factory ECU's built-in safety strategies. The result is stronger acceleration, increased torque, sharper throttle response, and factory-like drivability.
Installation is completely plug-and-play with a vehicle-specific wiring harness, requiring no ECU flashing, cutting, or permanent modifications. The system is fully removable and not VIN locked, making it an excellent option for enthusiasts who want maximum performance while preserving flexibility.
Included with every kit is access to the JB4PRO App for iOS and Android. Wirelessly connect to the tuner to switch performance maps, monitor live engine data, log performance, read and clear diagnostic trouble codes, update firmware, and analyze vehicle performance directly from your smartphone or tablet.
The JB4 includes multiple performance maps designed for various fuel types and performance levels, allowing your tune to grow alongside future modifications such as intake systems, intercoolers, exhaust upgrades, or ethanol fueling.
Designed, assembled, and supported in the USA, the JB4 has earned its reputation as the world's leading plug-and-play performance tuner, trusted by enthusiasts in more than 67 countries.

Why Choose JB4?
The JB4 is far more than a conventional piggyback tuner. By communicating directly with your vehicle through CANbus and multiple engine sensors, it continuously adjusts boost pressure, ignition timing, air/fuel ratios, and fuel trims in real time to maximize performance while maintaining factory reliability.
Unlike ECU flash tuning, the JB4 never overwrites the factory ECU software, eliminating concerns about permanently modifying or unlocking the ECU. The tuner is completely reversible, easily transferable to another compatible vehicle, and can be updated with new firmware and performance maps as Burger Motorsports continues product development.
