The disk is the DS downloader/interface program. It's not just for custom tunes, you need to get the latest CROM and update from DS, even though it's brand new, they don't have the latest tune/update on them, kind of a let down i know. If you try to load it right away without the update, the tuner will probably tell you need to update and then won't do anything.
