Hello, I tried to look for any information about this before making a new thread and it being my first thread. Well let me get right to it, I bought an sct x4 tuner for my 2013 ford Taurus sho. The error it is giving me when I go to program it is " vehicle unsupported" then gives me a KHDK4TA code. I wanted to know if anyone has run into these issues and what was a good way to resolve them.
