Remapping FAQs
Is remapping safe for my vehicle?
Calibration is safe when carried out on a mechanically healthy vehicle using professionally developed software. It will not repair or mask existing mechanical faults. The vehicle must be maintained correctly prior to modification.
Will you carry out a health check?
We do not perform mechanical strip-down inspections prior to tuning. It is the owner's responsibility to ensure the vehicle is in good working order. If warning lights, faults, smoke or abnormal noises are present, we reserve the right to refuse calibration.
How long does the process take?
Please allow up to 2 hours for most calibration appointments. Some vehicles may require additional time depending on software type and access method.
Can the vehicle be returned to stock?
Yes. Original software is always securely backed up and retained, allowing the vehicle to be returned to factory specification if required.
Do you offer finance?
Yes. 0% finance over 3 months is available via Payment Assist. Finance must be arranged and approved prior to your booking date.
Why have I not received a reply?
Common reasons include:
- Incorrect email address entered
- Reply delivered to spam/junk folder
- Vehicle not supported for calibration
All genuine enquiries are responded to.
Do you operate by appointment only?
Yes. We are strictly appointment-only. We are not a walk-in retail premises.
Can I remain with the vehicle during calibration?
No. For insurance and safety reasons, customers are not permitted in the workshop or inside the vehicle during the tuning process.
What happens if I arrive late?
Significant lateness may result in cancellation due to scheduled workshop workload. Missed appointments may result in loss of deposit.
How do I book?
Via our online booking tool or email/WhatsApp. Please don't try and book over the phone as you will be directed to our online booking system.
