Before you bookA few things
A few things
worth knowing.
Need help with something specific? Share your vehicle and question with the assistant, or call the team.
Ask about my vehicleDo I need my registration to explore packages?
No. Start with your make, model and year. We match the details you give us to the available vehicle records. Your registration is collected later for your enquiry; entering a registration does not automatically identify the vehicle.
Are the power and torque figures guaranteed?
Available figures are estimates for the selected vehicle variant, not a measurement of your individual vehicle. Condition, hardware, software and supporting systems affect the result. We confirm suitability before work proceeds.
What if my engine light is on or the car is in limp mode?
Tell us before selecting tuning work. The assistant will help establish the appropriate diagnostic route. An existing fault needs to be understood before remapping is considered.
What is the difference between Stage 1 and Advanced?
Stage 1 explores software tuning for a suitable vehicle with standard hardware. Advanced work covers more specific requirements, such as modified hardware or compatible TCU software. The exact work and price are agreed for the vehicle.
Which package suits everyday driving?
Economy focuses on efficiency, while Balanced explores usable performance alongside everyday driveability. Tell us how you use the vehicle and what you want to improve so the options can be assessed for you. Actual gains are confirmed individually.
Can I book a mobile visit?
Mobile appointments depend on your location, the service and a suitable place to work. Share your postcode during the enquiry. Available appointments and any relevant charges are confirmed before booking.
What happens if my exact vehicle is not listed?
You can continue with the details you know. The team can confirm the engine and software version before recommending the work. We do not substitute figures from a different vehicle.
