Fixing other companies shoddy work in this area for 17+ years!

Feel free to contact us if your car is suffering from another companies poor remap quality

Hello and welcome to CMR, a company specialised in vehicle remapping born in the heart of South West... Somerset! Primarily based in Yeovil and surrounding areas (but can cover places such as Dorset, Taunton, Bristol, Exeter etc)

If you've had a car remapped before then you'll be amazed at just how many places are now offering this type of service, well we've been around since the days of 'chip-tuning', for those that know a much more complicated process than today’s methods, and it's because of these ‘new-age’ simpler methods that unexperienced / unqualified people think they can simply jump on the band wagon and start offering remaps to the general public. What we tend to see is that these new companies buy cheap Chinese clone tools (copied tools made in china using inferior components compromising reliability and safety, they cost £50 and genuine tools cost £5000!) and they blindly flash poor quality tuning maps onto your car's ECU not knowing about any of the adjustments made, don’t get us wrong we get extra business putting these poor remaps right but it's always heart breaking to see someone’s pride and joy get damaged by someone out looking to make a 'quick buck'.

With CMR you'll have a Motorsport Engineering Degree qualified technician at your finger tips, you can ensure your car is in safe hands and will be treated with up most care and attention to detail. We have been remapping cars since 2007 and are now offering our services to the public as a part time small business. We take pride in our work and will only do the best job possible! So if you want to save fuel and gain power then get in contact today :)
