How would i find out if theres a programmer on my 05 cummins?? Theres already black smoke and it hauls ***.. The dealer said theres no program in it. So where would the plug in style chip go?

 

Mine smokes when i get on it nothin real thick but definately noticable and its stock-until tomarrow when i load up my new smarty on it! U have factory exhaust? I cut out the muffler and thats when it started smokin, not real sure why?
