I have the dealer tool and used it for my 500 mile service. It was pretty simple in operation, but I did run into a pitfall or two when getting it to work at first. The instructions for installing the software are a bit rudimentary.
I am absolutely available for any questions anyone might have, including what the capabilities of the software are and such. I have been using the TuneECU software for my Thunderbird for a number of years, and this software was very similar in capability, so it wasn't much of a transition.
