Hello, hey I wanted to ask if you were still noticing the ac issues. I have had my track key for a couple of months now and I am experiencing issues with the ac being cold then it goes to warm and muggy and back and forth intermittently. I wasn't able to test it accurately because I work only 1 mile from work. But in the last 7 days I had jury duty where I had to travel a great distance and used the track key for 3 days and had the same issues with warm muggy air intermittently. Tried the stock key the other 4 days and not once did I get warm and muggy air at all. Seems to happen more when I am off the gas pedal or when I am approaching a stop light in nuetral. Any feedback would be appreciated. I contacted Ford Racing and they are going to have Ray call me back since he was not in the office. Problem is definitely occurring with the tune. Now I know beyond a doubt.
