Mercedes-Benz remapping, mapped to your exact engine

Loaded is when it makes the most difference. A van that pulls properly from low revs needs fewer gear changes and less right foot to keep up with traffic, which is easier on the driver and usually on the fuel. Tell us the weight you carry and whether you tow, and the map is written for the van working, not empty.

The engine map is kept inside the torque your gearbox is built for. On a lot of these vehicles a gearbox map can be done as well, which firms up the shifts and stops it changing up too early when you are loaded. If yours cannot take one we will say so instead of taking the money.

Yes, and we would say that whatever the make. A remap is a modification, and insurers expect to be told about modifications. Most treat it as a straightforward declaration. We can give you the details of what was changed so you can pass them on, and the original file stays saved with us either way.

Technically yes, but be aware a modification can affect a warranty claim, and that is the manufacturer's decision, not ours. Your original software is saved, so the vehicle can be put back to standard before a dealer visit. If the warranty matters to you, speak to the dealer first — we would rather you asked than found out later.
