I actually have two questions. First will this tuner work on my 2010 GT? I hooked it up and it came on and I was able to get into the performance tunes the previous owner had on it (I did not load any). I just want to know if this tuner will work or will it mess up my car? Second question is; if it will not work, is it unlocked if I can get all the way into the tuning menus? I would like to know so when I sell it I can let the person know. Thanks everyone in advance.
