Before you book
How much does a remap cost?
Pricing depends on your vehicle, ECU and the work required. Send your vehicle details for a free quote, along with advice on the options available.
How much extra power will my vehicle make?
Potential gains vary by engine, original specification and vehicle condition. We’ll discuss an estimate for your particular vehicle. No performance figure is guaranteed.
Can you program a key for my car?
Coverage varies by make, model, year and key system. Tell us your vehicle details and whether you have a working key so we can check the available options. Proof of vehicle ownership is required for key work.
What should I check before having a remap?
Tell us about existing faults or modifications. You should also check insurance requirements and any manufacturer warranty or finance conditions before booking.
Can you help with AdBlue, EGR or DPF faults?
Contact us with the symptoms and any fault codes for advice on diagnostics and suitable fault rectification. Work for road vehicles must preserve applicable emissions compliance.
How safe are our tunes?
Experience behind the file.
Care behind the process.
We source our tuning files from a specialist company with over 15 years of file-writing and programming experience. We cannot disclose the company directly, but we are proud to work with a supplier whose expertise supports the service we provide.
At WAT, a professional tune starts with understanding your vehicle. We check its specification, discuss existing faults and modifications, and explain the suitable options before work begins.
Check first
Diagnostic health checks help identify existing issues before a calibration is installed. A tune should suit the vehicle’s condition, hardware and intended use.
Match the calibration
Correct ECU identification and a backup of the original software form part of our remapping approach. We work with vehicle-specific files and check compatibility before writing.
Verify and explain
Post-installation diagnostics and appropriate checks help assess the result. We explain expected gains and any limitations so you can make an informed decision.
No remap is completely risk-free. Results and reliability depend on vehicle condition, maintenance, fuel and use. Existing faults should be addressed first, and exact power figures require a dyno test.
