ive had this issue before, i swapped out colums and had the dealership reflash my pcm for the new ingintion because my truck wouldnt start. since i will be puttin the 5.3 pcm into the truck it wont jive with the ingintion/thieft system. ive also talked to three different tuners and they said they would have to reflash th pcm to bypass the thieft crap, maybe its not called VATS but it has to be done. also verfied by banker.
