The KLEEMANN Boost Kit raises the SC boost pressure to develop more power and torque across the entire rev range. The Boost Kit is a complete system, we start out with an OE Mercedes Benz crank pulley and increase the outer diameter of the SC drive plane. The pulley is dynamically balanced and all dampening features stay in tact. High Flow air filters are included with the kit, as well as any model specific hardware for the installation. A complete ECU remapping is done to support the new boost levels as well as improve throttle response, and raise the VMAX.
