Description
The Burger Tuning JB4 is the ultimate plug-and-play performance tuner for modern Acura turbocharged engines, delivering gains of up to +80whp/+100wtq on the 3.0L and +50whp/+60wtq on the 2.0L — all on a stock vehicle.
The JB4 connects to easy-to-access sensors under the hood and works alongside your factory ECU to optimize boost, timing, and fueling for maximum performance with reduced turbo lag. There’s no ECU flashing required, making it fully compatible with locked ECUs and completely removable without a trace.
With OBDII CANbus integration, the JB4 accesses real-time ECU data — including pedal position, throttle, fuel trims, AFR, knock, and more — allowing it to deliver smoother power, added safety systems, and advanced features like boost-by-gear, E85 mapping, and code reading/clearing.
