What are you looking to do? I ended up having my car remote tuned, but that's mostly because I wanted the guy that suggested the cam to do the tuning. Was pretty simple, just rented some dyno time and would do a run, send him the AFR chart, wait, load a new tune he would send, and repeat. Took a half day or so, but car is noticeably different than the base tune after the rebuild and drives much more like itself.
That being said, the dyno shop I went to was House of Boost. It was the most highly recommended shop by exotic owners in KC. Don't know how much tuning they do themselves though, if any at all.
