What is the JB4?
The JB4 is a true plug-and-play performance tuning system designed for turbocharged vehicles. Unlike basic performance chips, the JB4 uses advanced CANbus integration and direct sensor connections to safely and dynamically manipulate boost, fuel delivery, and ignition timing in real time.
It delivers gains comparable to ECU reflashing without permanently modifying or unlocking your factory ECU. Because it operates within the factory system framework, your vehicle retains all OEM safety protocols and smooth drivability.
The JB4 platform has been the global benchmark in plug-and-play turbocharged performance tuning for over a decade, continuously refined with free firmware and mapping updates.
