JB4 Group 9

Power gains of up to 100whp and 100wtq!

The JB4 is an easy to install plug and play tuner that attaches to sensors in the engine bay and works with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag. Includes full SENT sensor technology required for properly tuning the latest Audi platforms. Includes full CANbus allowing the JB4 to access and incorporate all engine data in its tuning strategies, incorporate unique safety features such as keeping boost pressure low until oil and water are up to temperature to provide proper engine and turbo lubrication, and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost. Includes fuel control for ethanol mixture mapping. Fully compatible with JB4 mobile for on-the-fly map changes, data logging, firmware updates, and much more. Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in the USA. 5-year warranty.




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. A separate JB4 Mobile app purchase is also required.
