Before booking a remap, ask what diagnosis, calibration work and testing are included. The location of the job alone does not establish the quality of the work.
Check who develops the file and who can revise it if the data shows a problem. A reusable calibration may suit a supported vehicle, but an unfamiliar hardware combination or existing fault needs assessment. Ask how the workshop checks fuelling, boost, temperatures and drivetrain limits.
Establish how the result will be measured, whether baseline data is recorded and what happens if a flash fails. Recovery tools and an appropriate power supply matter during programming.
Get the support terms in writing. Find out how a later warning or drivability issue is investigated, what software adjustments are included and which diagnostic or repair costs are separate. Emissions-system changes also need an explanation of their effect on the vehicle's compliance and use.
At Llandow, we develop calibrations in-house, use dyno testing and data logging, and discuss any underlying faults before further tuning. Contact us with the vehicle details to agree the work and its limits.
