This quick install plug and play tuner connects to four 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. Power gains range from 30-60whp depending map. 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 at some point in the future they will also migrate over. We'll update the model year compatibility details as we receive them.
