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.

You may consider the BMS Benz JB4 if you want to have maximum power!

You may also wish to add the Data Cable or the Bluetooth Connect Kit. This allows you to change the boost of the JB1.
