Had my BMW 420i remapped and gearbox software on 29/08/25. Customer service was great, and any questions I asked they were more than happy to explain. Absolutely transformed the car.
I booked in here with my 335d touring after reading the good reviews and I'm glad I did. Just the stage 1 and gearbox map has completely transformed the car. Incredible results.
I had my BMW E82 120d sorted here yesterday. After a terrible flash map I needed a custom tune. I am unbelievably happy with the results. Dan took his time to get it absolutely perfect.
I bought my new car that had a terrible MPG. I got 33MPG on the motorway to get the Remapping and 39MPG on the way home, with a noticeable improvement in power.
Great company! Very knowledgeable was a great experience highly recommended to anyone who wants the best out of their car!
Great service. Car is fantastic. No place I'd rather go to.
Legend — had it tuned locally elsewhere and the tune came with a lot of issues. He took it to stock and retuned it all while I watched Netflix in the room next door.
The only place to go if you have a BMW N57 35d engine. Took my F34 335d GT there with an existing aggressive flash map to get a smoother custom tune, xHP gearbox map and EGR solution. Achieved 388hp / 789Nm and transformed the car with xHP stage 3. Worth the 6 hour round trip.
Wow what a result — 45hp and almost 100nm increase on my 2018 BMW 520d Xdrive msport touring. Stage 3 XHP ZF gearbox tune as well and the 2 hour drive home on the M6 toll road was hella fun. TOTALLY transformed the way the car drives and responds.
What a great place to get your car remapped. Dan is a lovely guy who welcomes you and tunes your car safely. So happy with my BMW stage 1 — 388.9bhp with xHP, what a combo. Will be back for more in the future.
Booked my BMW 435D for ECU stage 1 and xHP stage 3 with DC. Just shy of 400HP and 800NM torque. After 100 miles I went to see full potential and couldn't be happier. Also noticed +4MPG in city driving. I can't recommend DC Remapping enough!
Spent time researching different remapping companies — DC Remapping stood out for their focus on data logging and health checks. Results came out at 332bhp and 720Nm. The car pulls incredibly hard, overtakes effortlessly. Stage 3 xHP gearbox transformed the shifts completely.
Amazing results on my BMW 335d F30 — achieving 388hp and 771nm stage 1 with the xHP stage 3 on the ZF8. Great customer service, travelled 5hrs round trip and I would definitely recommend. Transformed the car enormously.
Went in this morning to have a custom stage 1 on my G20 320i. Dan was very professional and welcoming when I came in, had it done within 2 hours and the results did not disappoint! I would highly recommend.
