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 BCM connections providing dramatically improved performance and smoothness over other 2-channel tuning systems.

Power gains are up to 50whp for the C300, up to 60whp for the C400/C450, and up to 70whp for the C43. On racing fuel or E85 mixtures even higher gains are possible.

Note 2019+ C300 models have changed to new SENT pressure sensors and require a unique JB4 system. Right now we believe all other 2019+ systems, C400, C450, C43, etc, continue to use the older pressure sensors but expect they will also migrate over at some point in the future. We'll update the model year compatibility details as we receive them. M264

Wirelessly Connect to your JB4: Our all-new JB4 PRO smartphone connection is included to wirelessly connect the JB4 tuner to your Bluetooth 4.0 compatible iOS or Android device. This option allows 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. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look. The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns.
