Typical before and after power and torque for every Rolls-Royce Phantom engine we tune. Your own car is custom mapped on our in-house 4WD dyno, and every map is fully reversible.
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 Phantom 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.

Rolls Royce Phantom remapping questions
How much power will a Stage 1 remap add to a Rolls Royce Phantom?
Gains vary by engine. The strongest on the Rolls Royce Phantom is the 6.75 V12, which goes from 563bhp and 900Nm to 700bhp and 950Nm, a gain of 137bhp. Find your engine in the table above for its own numbers.
What does a Rolls Royce Phantom remap cost?
Prices start at £1799 for Stage 1 on a Rolls Royce Phantom. Each engine in the table shows its own price. Bumper 0% finance over 6 months and Klarna are both available.
Does a remap invalidate the warranty or insurance on a Rolls Royce Phantom?
A remap is an aftermarket modification, so it is your responsibility to declare it to your insurer. It may also affect any remaining manufacturer warranty. Our maps are fully reversible: the car can be put back to its factory software whenever you need.
How long will my Rolls Royce Phantom be with you, and can it be undone?
Most Stage 1 tunes take around two hours, and if the ECU needs unlocking we do that on our own bench during the same visit, with no extra time. It is completely reversible: the car can go back to its factory software whenever you need.

Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna, or secure the slot with a £50 deposit. 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.
