It is my understanding that Jon Lund developed the tune, then SCT made a value file off of his ghost cam tune. Then sounding like the idle of the Boss 302 Ford had issues with it. I also heard the value file was incomplete since other things in the tune were changed that are claimed to not be available with the SCT software. But either way, you can no longer get these tunes.
I've communicated directly with Jon Lund on this issue. He stopped selling the tunes at the request of a friend who is a Ford Engineer. They have a long standing friendship. I think it was a stand up thing to do.
