    Just get a sports cat. Stay legal and still gain BHP.

    I dont see the point in running the car illegal for the sake of 5-10bhp.

    often the decat will cause the car to run wrong as the lambda sensor can pick up wrong signals

    karl is right, they have problems mapping the fuel towards the end of the rev range so it just runs rich.
