MJC Custom Remaps

second time of having MJC come out to do my cars and what a difference its made. They done a stage 2 engine and gearbox map on my BMW 645CI 4.4L V8. Its a completely different car now. If you need your car done I would highly recommend this company

What a fantastic family run business. I’ve just had my 535D M Sport + engine and gearbox stage 2 remapping done and what a fabulous difference it’s made to the overall performance of my car. A big shout out to the crew that came to my house to carry out the works very friendly and professional and the turn around from my call to them and the at home visit was amazing within 2 hours.

I will most definitely use them again and I will be recommended to all my friends.

A big thank you to MJC and team for coming out to re map my Audi A3 today! They come at short notice and had my car re mapped in no time. The team was so friendly was a pleasure to have them. They have made me love my car 100x more. Well recommend! Thank you once again many thanks Scott

Amazing customer service provided by MJC - super happy with the results of my Stage 1 Performance Remap and Gearbox Remap on my BMW. Highly recommended! Marco explained everything to me before the guys started and answered all the questions I had. 5 star service will defo be using them again 100%

Marco and one of his technicians came to my personal address at short notice. They arrived at 9pm after driving from out of London. Marco kept me informed of his arrival time so I wasn’t waiting around. Not only did I receive the most amazing service it was great to meet Marco and a member of his team. I would highly recommend MJC. My X5 is running beautiful, I could fell the improved performance from the off. I will be back for stage 2. Thank you for the service.

Today 23/11/2022 I got my Seat Altea FR remapped by this company and the service that I received was most definitely a pleasure. The team was extremely polite and friendly. They have put the kid back in me with my car and I have rekindled my love for my car. I will recommend this company and their services to anyone that is looking to use this company. Keep doing what you are doing MJC!!!!
Thank you once again.

MJC done it again! Previous dodgy coding was done to my car which messed up the map causing poor performance and economy, requested a reflash from MJC and they had me booked in very quickly to solve the issue. Drove down to the unit and found out the Ecu had been locked out because of this coding. Not a problem, very skilfully was able to connect directly to the Ecu and flash from there. Turns out the coding seriously messed up the existing file which caused errors. Because of this we had to reschedule so that they could work on the file to get rid of them. Very good communication from the team who kept me updated for when the file would be ready to upload. Went back down and the tune uploaded successfully with no more errors.

Would like to thank the team at MJC extremely, was very patient which the issue & knew exactly how to solve it. saved me a lot of money in the long run, had the car running the way it should producing a lot of power.

They really care for their customers ⭐️

Had my Audi Q5 remapped by this company and what can a say amazing customer service and value for money but most of all my car is shifting now. Had a stage 1 remapped and gear boxed mapped too, defo coming back when i upgrade to stage 2. Thanks again.
