I was one of the earlier customers to get a reflash and watched what was done to my car very closely. Hell, I even brought it back a week later to hook the data logger up and make a few runs on the street to make sure everything was holding up ok, as well as putting it back on the dyno a few months later to check.
No complaints here about the tune on my daily driver. If there was a bad spot in my tune, I would have found it by now.
