ok guys I recently bought this mbc and installed it, well Im having problems becuase when I turn the car on it idles very very roughly going from 300-1000 every couple seconds, looks like black smoke comin from exhuast very smelly, what I dont understand is why a boost controller would do this to my car when there is no -15psi going through my system when it is idiling? any ideas guys? thanks.
