Every price on this page is a full custom dyno tune
Not a generic file bought in and flashed over the port. Your Rolls Royce Cullinan 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 › Rolls Royce Cullinan remapping questions

How much does it cost to remap a Rolls Royce Cullinan?
Stage 1 custom dyno tuning on a Rolls Royce Cullinan starts at £1799 inc VAT. You can spread it over 6 months at 0%, or pay in 3 interest-free instalments with Klarna.
Will remapping my Rolls Royce Cullinan 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 Rolls Royce Cullinan 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 Rolls Royce Cullinan 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.
