The Burger Tuning JB4 for the Kia Stinger and Genesis G70 3.3L Turbo is a plug-and-play performance tuner engineered to deliver gains of up to 100hp and 100tq at the wheels on a completely stock vehicle. It connects directly to easily accessible sensors in the engine bay and works alongside the factory ECU to optimize boost, timing, and fueling. This reduces turbo lag while significantly improving overall engine performance.

Unlike basic performance chips, the JB4 utilizes a fully programmable CANbus system with firmware upgrade capability and advanced data logging. By reading pedal input, throttle position, gear, RPM, air/fuel ratios, fuel trims, ignition timing, knock activity, and more, the JB4 adjusts performance mapping precisely in real time. Built-in safety features monitor oil temperature, coolant temperature, lean conditions, boost levels, and knock—automatically reducing power if needed to protect the engine.

The default Map 1 adds approximately 4psi over stock boost, while additional maps—including stock mode and valet mode—can be changed on the fly using a diagnostics cable or JB4PRO wireless adapter. Installation is discrete and the unit can be removed without leaving a trace. Maps are included for 91 octane, 93 octane, and E85 mixtures. Normal driving fuel economy remains unchanged, and the tuner is fully compatible with all drive modes.

It is widely known that Kia and Genesis 3.3L Turbo engines can experience spark blowout at both stock and tuned boost levels. Spark plugs with more than 25,000 miles are recommended for replacement when increasing boost.

The JB4PRO smartphone adapter allows wireless connection to the JB4 using iOS or Android. The free JB4PRO app provides map control, data recording, firmware updates, log analysis, and a refined interface designed for easy use and high reliability.

What Is a JB4?

The JB4 is a plug-and-play performance tuner for modern turbocharged engines. It connects between the vehicle’s sensors and its ECU/DME, enabling performance gains through advanced signal interpretation and adjustment. The Burger Tuning JB4 stands apart from basic tuners with its CANbus integration, spark and fuel control, Bluetooth compatibility, fault-code management, and continuous mapping and firmware upgrades.

Burger Tuning provides ongoing free updates that enhance performance and add new features. The JB4 is not tied to a specific VIN, making removal, transfer, or resale easy. With more than a decade of development and distribution in over 67 countries, the JB4 remains the benchmark for plug-and-play turbo tuning systems worldwide.

The Burger Tuning JB4 for the 3.5L SmartStream Turbo V6 is a plug-and-play performance tuner designed to deliver gains of up to 100hp and 100tq at the wheels on an otherwise stock vehicle. Installation connects the JB4 directly to accessible engine sensors, where it works in conjunction with the factory ECU to optimize boost, timing, and fueling. The result is significantly improved performance, sharper throttle response, and reduced turbo lag while maintaining smooth OEM-like drivability.

Compared to basic piggyback chips, the JB4 advanced design utilizes a fully programmable CANbus system, allowing real-time adjustment based on throttle input, pedal position, gear, RPM, air/fuel ratio, fuel trims, ignition timing, knock feedback, and more. The JB4 also supports reading and clearing fault codes and includes comprehensive built-in safety protocols. These protections monitor oil and coolant temperature, boost levels, air/fuel ratio, and knock activity—automatically switching to a low-boost safety map if any unsafe condition is detected.

The default Map 1 increases boost by roughly 4psi over stock. Additional maps—including stock mode and valet mode—can be switched on the fly using a JB4 data cable or the wireless JB4PRO Bluetooth module. Maps are available for 91 octane, 93 octane, and E85 mixtures. Fuel economy during normal driving remains unchanged, and all factory drive modes operate normally.

The optional JB4PRO Bluetooth module allows wireless access from any iOS or Android device. The free JB4PRO app enables data logging, map selection, firmware updates, diagnostic functions, and advanced log analysis to evaluate performance and monitor engine health.

What Is a JB4?

The JB4 is an advanced plug-and-play tuning system for turbocharged vehicles. By intercepting and enhancing data between the engine sensors and ECU/DME, it enables safer and more sophisticated performance improvements than basic piggyback chips. The JB4’s CANbus integration, fuel and spark control, Bluetooth capabilities, safety systems, fault-code tools, and active development make it the most refined tuning module of its kind.

Burger Tuning frequently releases free firmware and mapping updates that expand performance and features. Since the JB4 is not VIN-locked, it can be removed, transferred to another compatible vehicle, or resold. With over a decade of development and distribution in more than 67 countries, the JB4 remains the global benchmark for plug-in turbocharged tuning systems.
