To grow our reputation as the most trusted performance tuning centre and specialist parts retailer in South Wales.


Nothing is someone else’s problem - this is the driving ethos behind our company supported by a spirit of teamwork, professionalism and accountability. By drawing upon our expert knowledge, experience and attention for every detail, we will grow our business and achieve our vision.


Indigo-GT was established in November 2005 by Antony James and Robert Williams, initially the company specialised in the sale of premium aftermarket parts for Mitsubishi Lancer Evolution's, within a couple of years and owing to demand from customers, Indigo-GT began offering servicing, maintenance and tuning primarily for Evo's and other performance Japanese cars from a small industrial unit in Merthyr-Tydfil.

Within just three years the company had grown considerably and by 2010, Indigo-GT occupied two separate units, one with a focus on MOT's and general servicing with the companies main unit being the focus of performance tuning and aftermarket parts sales.

By 2011, the company had physically run out of space and with a four wheel drive chassis dyno on the way from the United States, the company took a bold decision to move to a much larger site in Tredegar, with this move came new opportunities as the company diversified it's operations and began building it's reputation as a performance centre catering for a wide range of brands but with a heavy emphasis behind performance cars first and foremost.

In 2013 Indigo-GT became an Ecutek Master Tuner, having used Ecutek Software for a number of years to remap Evo 10's and later model Impreza's, the companies appointment as a Master Tuner allowed Indigo-GT to offer remapping of the stock Nissan R35 GT-R ECU, Indigo-GT remains the only Ecutek Master Tuner in Wales and one of just a handful in the UK.

The next major chapter in the story of our company came in November 2017 when we moved to a brand new 6,000 sq/ft unit in Ystrad Mynach, our new location gives us great access to to both the A470 and the M4 and serves as the perfect home for a new Dyno Dynamics 4WD rolling road seperated in it's own bay, our large workshop has five ramps in the workshop, a dedicated engine build room and spacious office. 

Our Team

Ryan Davies

Company Director

Ryan joined Indigo-GT in 2013 as a company director after working for an international manufacturing group that serves as a Tier 1 supplier to the automotive and aerospace industry.

Ryan has known Antony for over ten years dating back to his misspent youth when he used to own a Subaru Impreza Type R, his Impreza was one of the first cars Antony ever mapped, although that seems like a life time ago today.

Ryan's role within the company is focused around day to day operations including customer service related queries but he is also adept at technical sales and our remapping packages, you'll find him wrapped up in the corner of the office trying to stay warm... even in July.

Ryan currently drives a BMW M5.

Sam Dempsey

Vehicle Technician

Sam is the latest addition to our team, he joins us as a fully qualified technician with years of experience under his belt, in the relatively short time he's been with us, he's already proven himself to be incredibly capable and able to complete all the services we offer from advanced diagnostics to general servicing and repairs.

Antony James

Company Director

One of the founding company directors, Antony's role is focused around custom remapping for Evo's, GT-R's and Impreza's. His knowledge of Evo's (having owned several) is exemplary granting him the ability to offer our customers sound technical advice in support of the products and services offered by Indigo-GT.

Antony makes several trips across to continental Europe every year to remap customers cars, in addition to stock ECU remapping, Antony has a great deal of experience mapping Motec and Link ECU's for motorsport applications. If you visit Indigo-GT, more often than not you'll find him working on a car on our dyno.

Antony currently drives a BMW M2 Competition.

Damian Mason

Apprentice Vehicle Technician

Damien (who's actual first name is William) was the latest addition to the workshop team before Same arrived, having worked for his family business he's already more than capable of completing routine repairs and servicing, in the time he's been with us he's already grown his skill set considerably and has completed a number of SST gearbox rebuilds working far above the level of an ordinary apprentice technician.

Damien currently drives a Mitsubishi Evo 8.

Daniel joined Indigo-GT a number of years ago after taking a break from his career as a vehicle technician, in the time that Daniel has been with us, he's proven himself to be an incredibly capable and trustworthy colleague that's always prepared to go the extra mile in line with our customers expectations.

An integral part of our team, Daniel specialises in SST Gearbox Rebuilds and Evo X's which anyone that knows anything about Getrag gearboxes will tell you, is no small feat.

Daniel's day to day work involves routine servicing, maintenance and alignment using our Hunter system and other more complex tasks such as engine rebuilds.
