Who we are
A specialist you can actually trust
KP Tuning was set up to do one thing properly — mobile ECU remapping and diagnostics without the noise. No workshop you have to drive to, no upselling, no vague quotes. Just honest advice and clean work carried out at your location.
We're based in Flintshire and cover North Wales, Wrexham, Chester, the Wirral, Shropshire and Manchester. Every visit includes a free pre-tuning diagnostic check — we scan for fault codes and check key systems before we touch anything. If something needs dealing with first, we tell you.
We work on everything from daily drivers and performance cars to motorhomes and light commercial vehicles. If you're an enthusiast wanting more power, a driver wanting better economy, or just someone with a persistent fault light — we can help.
Dealer-level diagnostics
Same level of kit as main dealers. We read live data, clear fault codes and advise on the actual cause.
100% mobile
We come to your home, work or a workshop. No drop-off, no waiting around.
Custom remaps only
Every map is written for your specific vehicle and ECU data — not a generic file loaded off a shelf.
Honest advice
We tell you what's worth doing and what isn't. No pressure, no overselling.
