Is there any way I can tell if whoever owned my truck before me had a programer or any kind of module installed? I want to buy a new module but am worried i could be stacking it on top of an exsiting program.

 

well it would be easy to tell if they had left a module, cause it would still be there,,, once it is removed then it is removed. As for a programmer,, most likely there is nothing. If you dont get any smoke, I would bet that there isnt anything
