Gotech has everything you will ever need, i have the most basic ecu they do and its very good for the rs turbo, jamsport will fit and map it for you if you want, the ecu comes with a base map on and its very easy to go from there just plug your laptop in and start adjusting. My local rolling road took about 2 hours to get used to the software and thenn started mapping my car, said its very easy to use.
