Rolls-Royce Remapping Service
A Rolls-Royce should feel effortless, and a remap makes it more so: the same quiet, with more pull from low revs and a quicker answer when you press the throttle. The map is written in-house by a qualified motorsport engineer, with the same care as all our performance remapping, and smoothness comes first.

Why Remap Your Rolls-Royce?
Nobody buys a Rolls-Royce for lap times. The V12s gain torque low down, which is where a heavy car needs it, and the 8-speed automatic can be tuned to shift in step; our DSG/TCU remapping page explains how.
The Cullinan is all-wheel drive, so it goes on our in-house 4WD dyno with every wheel driving. We also remap Bentley, and BMW, which owns Rolls-Royce.
Rolls-Royce Petrol Engine Tuning
The Ghost, Wraith and Dawn use a 6.6 litre twin-turbo V12, and the Cullinan a 6.75 litre one.
Here are the 2 V12s at Stage 1, from the calculator:
- Cullinan 6.75 V12: 571 hp and 850 Nm as standard, 620 hp and 950 Nm at Stage 1
- Ghost 6.6 V12 (612 hp): 612 hp and 840 Nm as standard, 700 hp and 950 Nm at Stage 1
Both are typical for a standard car in good health, and a car like this is always checked over before its map goes on.

What happens on the day
Check your Rolls-Royce in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.
If your Rolls-Royce is an automatic, ask us about a gearbox (TCU) remap on the same visit.
