Plus Plus Calibration delivers Rolls-Royce ECU tuning nationwide for every modern model built around the twin-turbo V12: the Cullinan, Ghost, Phantom VIII, Wraith and Dawn, including Black Badge versions. Stage 1 and Stage 2 calibrations can be ordered online and done by mail.
A short history of Rolls-Royce
Charles Rolls and Henry Royce met in 1904 and founded Rolls-Royce in 1906, building a reputation for refinement that the Silver Ghost made famous. Since 2003 Rolls-Royce Motor Cars has been part of the BMW Group, building its cars at Goodwood in England.
Modern Rolls-Royces use twin-turbo V12s: a 6.6-liter in the first-generation Ghost, the Wraith and the Dawn, and a 6.75-liter in the Phantom VIII, Cullinan and second-generation Ghost. Black Badge versions, introduced in 2016, raise the output and sharpen the character.

Our online catalog covers these models, including Black Badge versions:

Stage 1 and Stage 2 Rolls-Royce tunes
A Stage 1 calibration works with the factory hardware on pump fuel, reshaping boost targets, ignition timing and torque limits; Stage 2 pairs the calibration with supporting modifications and high-octane fuel.
In our online catalog, a 2025 Cullinan goes from 563 hp to 715 hp at Stage 1 and 745 hp at Stage 2, and a 2022 Wraith is listed at 730 hp at Stage 2.
Rolls-Royce tunes in our catalog are ECU calibrations; there is no separate TCU add-on for these models.
Mail-in Rolls-Royce tuning
Mail-in tuning works from anywhere in the US. Order your Rolls-Royce tune online, ship us your ECU with your printed order confirmation email, and we calibrate it within two business days of receiving it, then ship it back at our cost. Inbound and return shipping transit time is not included.
Rolls-Royce tuning in our shop
Phoenix-area Rolls-Royce owners can bring their car to our shop. There, every calibration is checked on our in-shop dyno, with before-and-after dyno sheets, full data logging of air-fuel ratios, boost and knock, a written summary of every change, and a short road drive to confirm drivability.
