 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
