    Highly recommended service. The team at STX are very accommodating and professional. Had a remap on my Audi which was turned around in a day. Running perfectly. I will definitely be back for additional work in the near future.

    Had some work done by Sam and his team to my Skoda Superb. Flawless execution, better MPG and power delivery and no more engine lights. Communication was great - would definitely recommend and would use again without hesitation.

    Had my 2014 Golf GTI remapped by STX Tuning and I couldn’t be happier. The power gains are instantly noticeable—sharper throttle, stronger pull, and overall much more fun to drive. STX were professional and explained everything clearly. No issues since, and fuel economy is still the same. Highly recommend them if you’re looking to get more out of your car!

    I wanted to leave a genuine review, I got my car remapped on the 5th June 2026. Making the appointment was very easy, I didn’t have to wait too long for an appointment and had the option for someone to come to my house if needed. The remap was done within an hour or so. My light did come back on a week after the remap was done, but I was able to clear it with no issues and last weekend I took a 4 hour round trip to the beach and the light did not come back on when usually it does after about 1hr into a drive. The point of my long review is I highly recommend this company and I am very happy with the service provided.

    First time tuning my car. Didn’t know what to expect but it was amazing. They explained everything to me clearly, how it works etc and before you know it my car was ready. 10/10 polite service. Will be coming back in the future with serious motors, can tell these guys are professionals judging by tons of performance cars outside.

    Really five star service I’ve only got my car the day before I messaged on a Sunday just as an inquiry was more than Happy to take time of the day on a Sunday to fit me in last minute just want to think the whole team very professional and I absolutely love my car. I felt an instant power boost and explained everything to me and packages that I can definitely most likely in the future upgrade to will be definitely coming again.
