I need some help finding info on using a STAR DAS to deactivate the secondary air pump on our cars. I swear I read a post about this a year ago but I cannot find it anywhere and yes I searched, alot. If I remember right someone posted that you can deactivate the pump so the car can pass inspection. Does anyone know about this? I'm trying to help a friend with a C55. Thanks for any help.
