Description
The Burger Tuning JB4 Tuner for the Audi 3.0TFSI Supercharged engine delivers up to 45 wheel horsepower and 65 wheel torque on a completely stock vehicle, with even more power available when combined with bolt-on modifications, higher-octane fuel, or ethanol blends.
This easy-to-install plug & play tuner works seamlessly with your factory ECU, adjusting boost, timing, and fueling for optimal performance and reduced turbo lag—all while retaining factory smoothness and reliability. With full CANbus OBDII integration, the JB4 monitors and adjusts critical parameters like pedal position, throttle angle, timing advance, air/fuel ratios, knock detection, and fuel trims in real time.
Advanced safety features automatically keep boost low until oil and coolant reach safe temperatures, and the system will revert to a low boost map if it detects overheating, lean running, excessive knock, or overboost. The JB4 also supports fuel control for ethanol tuning maps, making it E85-ready.
Installation is discreet and reversible, with no ECU flash required. The JB4 is fully compatible with locked ECUs and leaves no trace when removed.

What is a JB4?
The JB4 is the most advanced plug & play tuning system for turbocharged and supercharged engines. It installs between the vehicle’s sensors and ECU, intercepting and adjusting performance parameters for maximum safe power.
Unlike basic piggyback chips, the JB4 uses real-time CANbus data, fuel and spark control, Bluetooth smartphone integration, and advanced safety protocols to deliver unmatched performance and drivability. Burger Motorsports regularly releases free firmware and mapping updates to improve features and power delivery.
