I would definitely recommend them and am well impressed with the remap they carried out on my W203 – the car absolutely flies now with stacks of torque and when she sprints its effortless….!!! – I used the mobile service and the technician Sam was fantastic and very professional and knowledgeable and really knew his stuff and was a really nice guy to. The price was fantastic too at £200 and he customised the remap and did not use generic files like a lot of companies do which are no good for the ECU. Sam added an additional 35BHP and 55NM of torque and took out all the flat spots. ECU Engine Remapping & Chip Tuning by Remap Science I was not happy with the level of customer service that I had received from the likes of the MLS Centre (who are based in the Midlands) and advertise in Mercedes Enthusiast Magazine and Carlson UK (authorised dealer based in Essex) as not only did they quote silly prices but also were not helpful and willing to give myself any knowledge and info on the actual remap and power gains and MSL were more interested in selling myself a new back box for the exhaust and K and N filters which are not good for Mercs – Carlson even wanted to remove the ECU which is not necessary at all and wanted the car for a whole day where the remap should take no more than an 1.5hr if being customised like mine was. The stealers were a joke as well wanted £1500plus for a Brabus box which does the same thing as a remap effectively does plus labour costs on top but I would only have gained an additional 25BHP and the parts dept were not able to advise me how much additional torque I would have gained.
