Practical information about the workshop, booking and what happens before tuning.
All bookings are carried out at Llandow Tuning in Llandow, Vale of Glamorgan. This page covers services for Cwmcarn drivers; it is not a separate Cwmcarn branch.
Yes. Cwmcarn is one of the towns covered by our Caerphilly service area. Start with your registration or vehicle details so we can check the available tuning options.
Courtesy cars are available by arrangement for suitable bookings. Ask when you contact the workshop so availability can be confirmed.
We review the vehicle, fault history, condition and intended use before recommending a calibration or dyno session. A generic package is not assumed to be right for every car.
Tell us what you drive and what you want to improve. We will advise on the next useful step.
