I am about to buy a used SCT TUNER. It is used and I am just making sure it will work in my car. As long as he puts his stock tune back in his I can program mine with it. His car is an 04 gt and mine is a 03 gt. Thanks.
well if he flashes his stock tune back then yes it is unlocked.
Will it work with your car. In theory. There have been several issues with 04's though trust me.
