About Majestic Tuning

At Majestic Tuning, we’re passionate about helping drivers get the very best from their vehicles. Based in Guildford, we provide professional mobile ECU remapping, diagnostics and vehicle services for customers across Guildford, Surrey and Reading, delivering high-quality workmanship with honest advice and outstanding customer service.

Our journey began with a genuine passion for cars and a strong mechanical background. With over ten years of hands-on mechanical experience and more than four years specialising in ECU tuning, we’ve developed the knowledge and expertise to safely improve vehicle performance while maintaining reliability. Since launching the business, we’ve proudly helped more than 800 satisfied customers achieve the results they were looking for.

Every vehicle we work on receives a full health check before any tuning is carried out, along with live data logging where required, ensuring your engine is performing correctly before software is installed. We use only genuine, fully up-to-date tuning software and professional master tools, allowing us to provide safe, reliable and bespoke solutions for a wide range of petrol and diesel vehicles.

As a fully mobile business, we bring our expertise directly to you. Whether you’re at home or work, we offer a convenient service with no call-out charges and flexible appointments between 8am and 8pm, seven days a week where required.

Customer satisfaction is at the heart of everything we do. That’s why every software solution is backed by a lifetime warranty and a 30-day money-back guarantee, giving you complete confidence in our work. Whether you need performance tuning, diagnostics, coding or mechanical repairs, we’re always happy to offer advice, answer questions and help you find the right solution for your vehicle.

We’re proud to be a growing local business built on quality workmanship, trust and a genuine enthusiasm for the automotive industry, and we look forward to helping you get the most from your vehicle.
