This quick install plug and play tuner connects to easy to reach plugs on top of the engine and safely increases turbocharger output by 3-6psi producing significant power and torque increases. Timing and fueling are appropriately rescaled for the increased boost and the installation is completely reversible in seconds. Compatible with all-wheel drive and rear-wheel drive models. The JB4 is the only tuning system that includes CANbus and optional wastegate connections providing dramatically improved performance and smoothness over other 2-channel tuning systems.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase is also required.

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.

What Does Burger Motorsports Offer?

Apart from tuners, Burger Motorsports also designs and manufactures air intakes, catch cans, and exhaust tips. Its N55 air intake has been proven to outperform all other options on the dyno with gains of up to 10 horsepower to the wheels. Burger’s vehicle-specific intakes are super simple to install and yield impressive power gains due to their high-flow ducting and performance filters. 

BMS’ oil catch cans are designed to counteract the common oil control problems that several turbo motors suffer. Using 100 percent CNC machining and zero weldings for a precise fit, Burger’s catch cans are guaranteed to last the lifetime of your car. They are also really simple to install thanks to their removable bottom and built-in plug that allows for easier draining during oil changes.

Burger Motorsports also features a wide array of custom exhaust tips in different colors that range from heat-treated blue to matte black. These tips will subtly transform the look of your car’s rear while giving it a more aggressive appearance. BMS exhaust tips all utilize a pressure-based clip similar to the OEM ones for an easy installation and removal process that does not require any unappealing clamps or screws.
