The 1.8T BCS (Boost Control System) is designed to work with all throttle-by-wire Audi and Volkswagen 1.8T engines. Compatible models include the A4, Beetle, Passat, Jetta, Golf and GTI. The BCS provides user adjustability of maximum boost. At the minimum setting, the boost is held to the stock level of 6 PSI and the car will drive exactly like a stock car. As the boost setting is increased, the allowable boost is increased in precise increments. At the maximum setting, the boost is allowed to reach 14.5 PSI. This boost increases horsepower by 30 hp and the low-end torque is increased by 45 ft-lbs. The BCS includes a ten segment, three color LED boost gauge that reads in 1.5 PSI increments from 1 to 14.5 PSI. The display is electronically filtered to provide a smooth reading.

The BCS offers an alternative to aftermarket re-programming of the ECU. With the BCS, the stock ECU programming is maintained. This helps to preserve smooth and predictable drivability.

The BCS is easy to install. Its small size makes it easy to fit in the center console. The six wires leading from the BCS are all connected to the car’s wiring harness at one location.
