I would say be up front with your dealer I can see ford not covering tunes if they are not safe ones but we are putting on safe tunes here it's never a good idea to lie or try to hide stuff that is what's wrong with this world. ford has to protect themselves from craziness if your dealership is ok with mods if they put them on and don't find you put a different one on all should be good I don't get why any one would try to take it off if you have the dealership put it on they know it's safe or wouldn't do it.
