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 AMG GT 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, ignition timing, fuelling, knock and temperatures all watched in real time while the car is running under load.
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 £166.50/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 ›

Will remapping my Mercedes-Benz AMG GT 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 AMG GT 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 AMG GT can go back to its factory software on request.
