Evolution dealers all have a handset known as a "genius" which is very similar to a bluefin in many ways, but they can load any map from any car onto it that evolutions give them access to, and all dealers can then request specific changes to be made to the file itself if they require as well, so its basically an off the shelf map service for good quality initial maps, but with the ability to custom tune as well.
Powerful setup, but not just cause of the hardware, cause of the skills of Kenny and Stu in mapping in the first place. Ultimately whatever the tools are it still falls back to the people actually doing the maps!
