Standard hardware is a starting point
For a healthy standard car, discuss the available ECU route and the response you want from everyday driving. The registration, engine and transmission help identify support. Service history and current concerns help establish whether tuning is the appropriate first job.
Modified parts change the brief
An intercooler, turbo or fuel-system change needs identifying by the fitted specification. A Stage 2 label cannot describe every build. List the hardware and fuel so the calibration can be discussed against the car as it is today.
Already tuned?
Include the previous tuner and any invoice or report. Say whether the car drove differently after the software or a later part was fitted. An unknown calibration and a running symptom need a clearer history before another tune is selected.
Agree how the work will be assessed
Ask which checks and measurements form part of the proposed appointment. If the engine hesitates or loses power, explain that as an investigation rather than treating another power target as the answer.
Use the existing-remap checklist, discuss custom hardware or include the transmission in a gearbox enquiry. Send the specification before booking.
