Car remapping and tuning for Llantwit Major drivers
Llantwit Major drivers use the physical Llandow workshop shown on this page; there is no branch in the town. Send the vehicle details before travelling so we can check the supported options and whether diagnostics or dyno work belongs in the booking. Use current directions for the journey because road conditions and the best route can change.
All bookings are completed at our Llandow workshop. Start with the exact car and the result you want, and we will explain the most suitable route before any work is agreed.

Workshop route
From Llantwit Major to the Llandow workshop

All diagnostics, in-house ECU calibration and dyno-supported work is carried out at Llandow, so this page is a route to that workshop rather than a claim of a second branch. Confirm the vehicle and appointment first, then use current directions for the local journey.

Before you travel
Questions from Llantwit Major customers
Practical information about the workshop, booking and what happens before tuning.
Where is Llantwit Major remapping carried out?
All appointments are completed at Llandow Tuning in the Vale of Glamorgan. This page covers the service for Llantwit Major drivers; it is not a separate Llantwit Major branch.
What should I send before booking?
Send the registration or full vehicle details, the intended use and any warning lights or existing modifications so we can advise on the useful next step.
Can I book diagnostics and tuning together?
We can discuss the concerns first and plan the right workshop appointment. A calibration is not assumed to be the answer until the vehicle has been considered.
How should I plan the local journey?
Confirm the appointment and use current directions to the Llandow workshop. The best route and road conditions can change, so we do not state a fixed travel time.
