Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your Mercedes-Benz B-Class is strapped to our in-house 4WD dyno and the map is written for your car, on the day, from its own data.

Health check firstWe look the car over and read the fault memory before we touch anything. If something is wrong, you get told. We don't map over a problem.
Live data loggingBoost, timing, fuelling and temperatures all watched in real time under load: knock on the petrols, rail pressure and exhaust temps on the diesels.
Custom calibration on the dynoThe map is built and adjusted run by run against what your engine is actually doing, not what a file supplier assumed.
Before and after printoutYou leave with the graph: your standard figures and your tuned figures, measured on the same rollers, the same day.

Spread the cost. From £91.50/mo over 6 months at 0% APR with Bumper, interest free.
Split your purchase into 3 interest-free instalments with Klarna. Borrowing more than you can afford or paying late may negatively impact your financial status and ability to obtain credit. Subject to status. Ts&Cs and late fees apply.
For Klarna, choose Pay in full when you book. How finance works ›

Mercedes-Benz B-Class remapping questions

How much bhp does a Mercedes-Benz B-Class gain from a remap?

Gains vary by engine. The strongest on the Mercedes-Benz B-Class is the B 160 1.6, which goes from 102bhp and 180Nm to 175bhp and 300Nm, a gain of 73bhp. Find your engine in the table above for its own numbers.

What does a Mercedes-Benz B-Class remap cost?

Prices start at £549 for Stage 1 on a Mercedes-Benz B-Class. Each engine in the table shows its own price. Bumper 0% finance over 6 months and Klarna are both available.

Does a remap invalidate the warranty or insurance on a Mercedes-Benz B-Class?

A remap is an aftermarket modification, so it is your responsibility to declare it to your insurer. It may also affect any remaining manufacturer warranty. Our maps are fully reversible: the car can be put back to its factory software whenever you need.

How long will my Mercedes-Benz B-Class be with you, and can it be undone?

Most Stage 1 tunes take around two hours, and if the ECU needs unlocking we do that on our own bench during the same visit, with no extra time. It is completely reversible: the car can go back to its factory software whenever you need.
