I decided to go different route. I have up for sale a SCT x4 handheld tuning device. It has the pre-loaded tunes for the 2013 and before models. It does work on the 2014 and up models. But only difference is the pre-loaded tunes don't work on newer models. I am also attaching a link to sct's website. You can look it up if it'll work for your particular vehicle.
