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 A-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 A-Class remapping questions

What does Stage 1 tuning do for a Mercedes-Benz A-Class?

It depends which engine you have. Across the 47 Mercedes-Benz A-Class engines we tune, the A 45 AMG sees the biggest Stage 1 gain: 387bhp to 470bhp and 480Nm to 620Nm, up 83bhp. Every figure on this page is for that exact engine.

How much does it cost to remap a Mercedes-Benz A-Class?

Stage 1 custom dyno tuning on a Mercedes-Benz A-Class starts at £549. You can spread it over 6 months at 0% with Bumper, or choose Pay in full when you book and pay with Klarna.

Will remapping my Mercedes-Benz A-Class affect my warranty or insurance?

You will need to tell your insurer, as with any modification, and it can affect a remaining manufacturer warranty. Every map is reversible, so the Mercedes-Benz A-Class can be put back to its factory software at any point.

How long does it take, and is it reversible?

Allow roughly two hours for Stage 1, including any ECU unlock on our own bench. Everything is reversible: the Mercedes-Benz A-Class can go back to its factory software on request.

Figures are typical for a healthy, standard vehicle; your before and after dyno printout shows exactly what your car makes. Your car’s actual output depends on its condition, fuel quality and any supporting modifications. Prices shown are for Stage 1 custom dyno tuning; locked ECUs (most BMW and Audi registered from mid-2020) carry an additional unlocking charge, confirmed when you book.
