Description
Experience the ultimate performance upgrade for your Chevy Colorado with the Burger Tuning JB4 Tuner, delivering gains of up to 85whp and 120wtq on a completely stock truck — without the risks associated with ECU flashing.
The JB4 is a plug-and-play tuning system that installs in minutes by connecting to two easily accessible sensors in your engine bay. It works seamlessly with your factory ECU, optimizing boost, timing, and fueling for maximum power, sharper throttle response, and reduced turbo lag.
Unlike permanent flash tunes, the JB4 is fully removable and leaves no trace. Your vehicle remains unaware of the performance increase, maintaining stock reliability and warranty compliance. Fuel economy remains unchanged during normal driving, and the JB4 is fully compatible with all drive modes — including towing.
Advanced CANbus Integration
The JB4’s integrated CANbus technology allows it to read and process real-time data directly from the ECU — such as throttle position, timing advance, pedal input, fuel trims, AFR, knock feedback, and more. This live data enables precise and adaptive tuning, ensuring smooth power delivery and exceptional safety.

What is a JB4?
The JB4 is the industry’s most advanced plug-and-play performance tuner for turbocharged vehicles. It intercepts and optimizes signals between your vehicle’s sensors and ECU to enhance performance, all while maintaining factory safety parameters.
Unlike generic tuners, the JB4 uses advanced processing, CANbus integration, and Bluetooth connectivity for superior control, safety, and adaptability. It’s not VIN-locked, allowing you to remove, resell, or transfer it to another compatible vehicle.
