tune issue?

cammed and tuned my ss bout a month back, sometimes after reving it,it idles back down but falls back down to like 500rpms almost like its gona cut out and them slowly comes back up. and wen it does this the car smokes a little and the car also smokes wen just idling normal why is this? and all the valve seals are new so i dont think its something of that nature
