Ask about your vehicleDo you offer mobile appointments?
Yes. Appointments may be available at your home or workplace across England and Wales.
What hours are appointments available?
Appointments are typically available from 7am to 10pm, depending on location and availability.
Is my vehicle suitable for remapping?
Suitability depends on the exact model, engine, ECU, software, condition and existing modifications. Call with your registration so compatibility can be checked.
Is finance available?
Finance options may be available, subject to approval, eligibility and provider terms.
Do you offer DPF cleaning?
Diagnostic and cleaning support may be available for suitable diesel particulate filter systems. The vehicle must be assessed first, and cleaning may not resolve every fault.
Will remapping affect my insurance or warranty?
You should tell your insurer about relevant modifications. Modifications may also affect a manufacturer or third-party warranty, so check the applicable terms before proceeding.
Are results guaranteed?
No. Results vary with the vehicle, condition, software, fuel, modifications and driving style. No fixed power, torque or economy result is promised.
