I’m not an RS owner but I do work on a few of them, I run a tuning company in Scotland where we cater for a wide variety of marques and the MK3 RS is one of them thanks to one of our suppliers Motorsport Developments (MSD), we are an agent for their remote remapping service Evolution Chips. I’ll not name my own company since this is usually frowned upon on forums but there’s not many Scottish tuners for Fords so it’s easy enough to work out 😉
