Services

Remapping

Our IMI-certified engineers optimise engine performance through custom ECU remapping. Using a Dynostar rolling road, we achieve up to 70% more power and 15% fuel savings while maintaining safety limits. Each remap includes pre/post performance testing with printed graphs for verification. We offer three tuning options: High Power, Power/Eco Blend, and Maximum Economy to suit different driving requirements.

DPF Cleaning

We employ advanced cleaning technology to restore diesel particulate filters to 98% of original efficiency. Our process includes pressure testing at 90C to identify hidden cracks and vacuum testing for valve integrity. All DPF cleaning comes with a 1-year guarantee and includes flow rate verification before and after treatment to ensure optimal performance.

Diagnostics

Our diagnostic service utilises top-tier equipment for identifying complex engine management issues. Using live data testing on our rolling road, we simulate real driving conditions to pinpoint intermittent faults. This approach resolves recurring problems efficiently, saving time and costs while providing detailed analysis of ECU error codes and sensor performance.

Cylinder Head Skimming

We offer precision cylinder head skimming and testing services to address warping and internal leaks. Our Delta Pressure Testing rig identifies cracks invisible to conventional methods. The service includes 24-hour turnaround for head skimming and vacuum testing to ensure valve integrity, maintaining engine reliability and performance.

Advanced Tuning Boxes

Our plug-and-play tuning boxes deliver up to 70% power increases with DPF-friendly settings. Featuring five user-selectable modes from economy to performance, these microprocessor-based units offer precise boost control and reprogrammability for future vehicles. Installation is free, with custom software calibration to match specific engine requirements while maintaining emissions compliance.

Following breakdown, excellent service from the initial call to enquire whether the required job could be undertaken, being recovered from home and subsequently informed the car was ready for collection. Many thanks Alex. I can highly recommend CMS.

I had a blocked DPF on my Jaguar XF and called CMS to get some advice. They were able to remove and clean the DPF filter and it is now as good as new. Would highly recommend, and will use them again. Thanks Richard for the great service.

Having used CMS 3 times for a remap now - I think it's about time I gave my honest review of how genuinely great my experiences have been here. The remap service provided has greatly improved the performance and drivability of my VW Phaeton - and to be honest you don't realise how much power you're missing out on until you've had a remap done! I opted for the blended map which has given me a huge performance gain and a bump in fuel economy to boot. It drives like a completely different car. I was also offered an economy remap and an all out performance remap. My latest visit was a testament

Today I took my 4.4 petrol Discovery to CMS for an engine remap. This is the second time i have used the services of Richard and Alex to remap my cars. I first took in my other car a Range Rover 3.6 Diesel , which at the time thought was running fine, only I did want to have an EGR delete done. which they did at the same time. The level of service you get from these guys is second to none and the knowledge of each vehicle is fantastic. Before you even book in your car, they will give you an honest opinion and value of what can be achieved from the remap. With both of my vehicles the difference
