Your local tuning and servicing experts in High Wycombe

Refined Tuning Autocentre started with a passion for tuning and grew into a full independent garage on Ford Street in High Wycombe. Over more than ten years we have built our name the hard way, one happy customer at a time, by doing good work at a fair price and being honest about it.

We offer professional vehicle tuning and maintenance using modern diagnostic tools and quality OEM parts. From remapping for more power or better economy, to diagnostics, DPF and EGR solutions, servicing, MOT repairs, tyres and air conditioning, we look after all makes and models.

Our aim has never changed: to build long-term relationships with the people we look after. That means transparent advice, fair pricing, and a satisfaction guarantee on our remapping work, so you can come back to us again and again with confidence.

Our workshop is run by a team of experienced technicians who genuinely enjoy the job, whether that is tracking down a tricky electrical fault or rebuilding an engine. Customers regularly name CJ, whose diagnostic work gets a special mention, and Sunny, who is known for being endlessly helpful and quick to answer any question.

We also invest in modern equipment and keep learning, so we can look after newer vehicles as well as the classics. Whoever you deal with, you will get the same friendly, honest service, and a clear plan for getting you safely back on the road.
