Also, if anyone is interested in the XDF's and information I have on the '411 so far, just let me know where I can post them or share them. I love this forum (and those like it) that help to share the knowledge of how to self tune these PCM's w/o having to pay for the individual licenses for the other tuners. There's so much that's in theses PCM's that can be used and enabled whether or not the factory gave it as an option on a particular vehicle.
