Common Questions

Questions Answered

Everything you need to know before booking. Still not sure? Give us a call.

Most standard remaps take 1–2 hours. Complex Stage 2 or custom tunes may take a little longer. We give you a clear time estimate at booking.

Remapping under manufacturer warranty may affect it — we advise checking with your manufacturer first. Once expired, no concern. We always back up your original map.

Both. Our Ammanford workshop has the on-site MAHA 4WD dyno for jobs that need it. For most remaps, coding and security work our mobile team comes to your home or workplace across South Wales.

Yes, when done correctly. We prioritise engine health and driveability alongside performance. Your original map is always backed up and can be restored free of charge under our lifetime warranty.

Stage 1 is software-only — no hardware modifications required, pure bolt-on gains. Stage 2 pairs software with hardware upgrades (exhaust, intercooler etc.) for larger results. Use the Tuning Calculator to see figures for your vehicle.

Any performance modification should be declared to your insurer — failure to do so could invalidate your policy. Many insurers accept remaps with little or no premium increase. Economy remaps can sometimes reduce premiums.

Absolutely. We back up your original ECU map before we begin. You can request a full return to factory settings free of charge at any time under our lifetime software warranty.

Our workshop is in Ammanford (SA18 1PA). Our mobile team regularly covers Swansea, Neath Port Talbot, Carmarthen, Brecon and surrounding areas. Not sure? Call or message us.
