Not a generic file bought in and flashed over the port. Your Bentley Mulsanne 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.

Will remapping my Bentley Mulsanne 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 Bentley Mulsanne 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 Bentley Mulsanne can go back to its factory software on request.

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.
