look under your hood for a chip...map sensor near your rail and injectors. if it has a chip youll see the extra conections and so forth.. or look near the steering wheel or by your knees...if you see a small hole with a switch they probably had one there at one point..the adjustable type. and as with tuner? get your ecm checked..not sure if there is any other way good luck
