Mercedes-Benz Remapping Service

A Mercedes-Benz remap gives you more pull when you ask for it, easier overtaking and, in a diesel, better economy on a steady run, while the car stays as smooth and quiet as Mercedes made it. Every map is written in-house by a qualified motorsport engineer for your car or van.

Why Remap Your Mercedes-Benz?

Mercedes builds its cars for comfort and long distances, and a remap makes that even more relaxed: more torque low down, fewer kickdowns on hills and an easier time with a trailer. Most automatic Mercedes models from the last decade use the 9G-Tronic gearbox, which can be tuned alongside the engine through our DSG and TCU remapping. 4MATIC cars go on our 4WD dyno with every wheel driving, before and after.

Mercedes-Benz Diesel Tuning

From the 200d and 220d in the A, C and E-Class to the six-cylinder 350d and 400d in the GLE and S-Class, Mercedes diesels gain mid-range pull and overtake more easily. The Sprinter, Vito and Citan gain pulling power when loaded, and our van remapping page covers commercial use.

From the A200 to the AMG 45, 63 and GT, petrol Mercedes get more power and a quicker response. Our performance remapping page covers the AMG cars and what's possible beyond Stage 1.

What happens on the day

Check your Mercedes-Benz in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.

If your Mercedes-Benz is an automatic, ask us about a gearbox (TCU) remap on the same visit.
