Every price on this page is a full custom dyno tune
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.

How finance works › Bentley Mulsanne remapping questions
What gains can I expect from Stage 1 on a Bentley Mulsanne?
It depends which engine you have. Across the 2 Bentley Mulsanne engines we tune, the 6.75 V8 Bi-Turbo sees the biggest Stage 1 gain: 537bhp to 650bhp and 1100Nm to 1300Nm, up 113bhp. Every figure on this page is for that exact engine.
How much does it cost to remap a Bentley Mulsanne?
Stage 1 custom dyno tuning on a Bentley Mulsanne starts at £1299 inc VAT. You can spread it over 6 months at 0%, or pay in 3 interest-free instalments with Klarna.
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. Because we save your original software first, the Bentley Mulsanne can be put back to standard at any point.
How long does it take, and is it reversible?
Allow roughly two hours for Stage 1, or a half-day if the ECU needs unlocking first. Everything is reversible: we store your original software so the Bentley Mulsanne can go back to stock on request.

Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna (3 interest-free payments), or secure the slot with a £50 deposit. Figures are typical results for a healthy, standard vehicle on our dyno. Your car’s actual output depends on its condition, fuel quality and any supporting modifications. Prices shown are for Stage 1 custom dyno tuning inc VAT; locked ECUs (most BMW and Audi registered from mid-2020) carry an additional unlocking charge, confirmed when you book.
