Product Description
The JB4 is the most advanced and highly featured tuning system available for your 2017+ Alfa Romeo Quadrifoglio 2.9L 6-cylinder twin turbo. Power gains are up to 80hp on a completely stock car on pump gas. Gains with bolt-on parts, higher octane, and larger turbos are even higher.
The JB4 Tuner features a simple plug and play installation harness for easy installation and removal and includes many features not found with any other tune. Including on the fly map switching from your phone/tablet between factory and various performance maps, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, and much more.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit or 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.
