Does anyone know if there is a company that makes and an EGR simulator for a 1999 5.7L 350 Vortec in my Suburban. I got a set of headers but they do not have the air tube for the EGR. The vehicle runs great just here in NY if the Check engine light is on it wont pass inspection. I either need a simulator or someplace that can reprogram my ecm so it does not need the sim.
