Hey guys does anyone know where i can buy an upgraded wastegate (i.e a better than stock one) actuator for my euro4 smart 451 turbo non brabus. Im looking to buy a pipercross filter , turbosmart boost control, some NGK iridium laser ILKR7B8 (colder plugs)and a re map but need help on the wastegate actuator. I could see figures of up to 133hp looking around 0.6-1.0 boost with this setup . any help and opinion is welcome.
