Car remapping and tuning for Swansea drivers
Every Swansea booking is carried out at our Llandow workshop, not at a Swansea branch. Send the registration, relevant modifications, warning lights and the result you want before setting out so we can check the supported service and plan the appointment. Journey conditions vary, so use current directions when planning the visit.
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
Plan a Swansea tuning visit to Llandow
A Swansea booking involves bringing the vehicle to our Llandow workshop. Before setting out, send the registration, engine or gearbox details, modifications, current faults and the result you want so we can check the appropriate workshop route. Diagnostics, in-house calibration and on-site dyno facilities are then available in one location where the vehicle and booking require them.
Describe faults and modifications
Known warnings, previous tuning and hardware changes can alter the right first step, so include them when making the enquiry.
Dyno use is vehicle-led
On-site dyno testing is available, but it is planned where the car and the purpose of the booking make measured testing useful.
Common makes and faults
AdBlue, DPF and EGR help for popular makes in Swansea

Before you travel
Questions from Swansea customers
Practical information about the workshop, booking and what happens before tuning.
Do you have a remapping branch in Swansea?
No. Swansea is a service area for our one physical workshop at Llandow, where all tuning, diagnostic and dyno work is carried out.
What should I confirm before travelling from Swansea?
Send the registration, exact vehicle details, modifications, known faults and the result you want so we can check the relevant service and plan the appointment.
Can diagnostics and tuning be discussed together?
Yes. The workshop can assess whether a fault needs investigation first and whether calibration or measured testing is appropriate afterwards.
Is a dyno run automatically included?
Not automatically. The useful testing route depends on the vehicle and the aim of the booking; on-site dyno support is available when appropriate.
