Car remapping & ECU tuning in London
Stage 1 and Stage 2 remaps, DSG and gearbox tuning, and tailored performance calibration for cars and vans.
Professional tuning, built around your vehicle
Diagnostics first, vehicle-specific calibration and genuine professional tuning tools.
Advanced diagnostics
Vehicle health checks before calibration work begins.
Custom tuning files
Vehicle-specific calibration rather than a generic file.
Developed performance targets
Measured, realistic gains matched to the vehicle setup.
Genuine tuning tools
AutoTuner, Alientech KESS3 and Magic Motorsport FLEX.
From first scan to final road test
Every vehicle is different. Our workflow starts with diagnostics, moves through a vehicle-specific ECU read and calibration, then finishes with validation and a road test where appropriate.
Health check first
We scan the vehicle, check relevant fault data and confirm the car is suitable before calibration work begins.
Read the original calibration
Using supported professional tooling, we read the ECU through the correct OBD, bench or boot method for the vehicle.
Calibrate for the vehicle
The map is developed around the vehicle, requested stage and safe operating targets rather than applying a one-size-fits-all file.
Review the expected result
Power and torque targets are vehicle-specific. Our lookup helps you compare stock figures with estimated tuned output before you book.
Validate the final result
Where appropriate, we complete final checks and a road test to confirm drivability and the requested calibration outcome.
See your vehicle's stock and tuned potential
We avoid generic headline claims. Use the vehicle lookup for model-specific stock BHP/torque and available tuning estimates, then request a quote for your exact vehicle.

Steps we take to remap
Diagnostic & read ECU
BOOST REMAPS supplies custom remapped tuning files. First, we do the diagnostic to see if there are any sort of major fault code on the car which may interfere ECU writing process.
Original ECU files
We extract the original file from the ECU (Electronic Control Unit) of the vehicle using Autotuner or Kess V3 or Flex. We use 100% Genuine hardware and software to do the ECU reading & writing.
Modify & write file
Finally, we modify the ECU file and write back into your car and are good to go with better performance. We work with WinOLS authorised partner.

I had a great experience with Boost Remaps today. They were extremely helpful from start to finish, taking the time to explain every step in detail and showing me exactly what was being done. They carried out a DPF, EGR and swirl flap delete, followed by a Stage 1 performance map. The first map my car received wasn’t accepted by the ECU, but instead of rushing the job, they took the car out for a test drive, carried out diagnostics, and created a completely new map. My car accepted the new map without any issues, and it’s now running perfectly. The customer service was excellent throughout. They kept me informed, answered all my questions, and even said to get back in touch if I have any issues with the map in the future, which gives great peace of mind. They also completed an eco map on my brother’s car, and he was just as pleased with the service. Overall, a professional, knowledgeable, and genuine company that clearly cares about getting the job done properly rather than taking shortcuts. I wouldn’t hesitate to recommend Boost Remaps to anyone looking for quality remapping and excellent customer service.
Came here for a Stage 1 on my BMW 320d and I’m genuinely impressed. Mohammad took his time, listened properly to what I wanted, and explained everything clearly before doing anything. You can tell he actually cares about doing the job right, not just rushing cars in and out. What I liked most is that this isn’t one of those places that just throws a generic file on your car. He works with your actual ECU file and makes sure the setup suits your car and how you want it to drive. The result feels smooth, strong, and safe exactly what I asked for. The car drives completely different now, in a good way. No issues, no stress, just proper performance. Honestly, 10/10 from me. If you’re in London and thinking about a remap, this is the guy to go to. If you want, I can make a shorter Google review version or a more aggressive “sales-type” one depending on where you’re posting it.
I had my BMW Stage 1 ECU tuned with Mohammed. He was very polite and willing to explain the technical process to me which assured me it was being done professionally. He also managed to book me in very quickly on late notice after our phone call which was much appreciated. Not to mention his competitive pricing as well , though the quality is of the best! I definitely did notice a difference in the smoothness of the acceleration during the drive after, as I was not necessarily targeting pure speed. Thank you Mohammed and Boost Remaps.
Great experience with Boost Remaps. I brought my Range Rover Sport in, and the whole process was very professional. They explained every step clearly and made sure I understood everything. Any issues that came up were handled quickly and efficiently. After the remap, the performance improvement is very noticeable — the car feels much more responsive and powerful. Highly recommended!
Excellent service! Had a major AdBlue issue on my DS7 with a '50-mile no start' warning. The technician was very professional, used high-end diagnostic tools, and stayed until the job was 100% finished. The car is running perfectly now. Highly recommend!
