    STX Tuning were absolutely brilliant. The service was super fast — same day turnaround — and they solved an issue with my car that a main dealer claimed would cost me thousands to fix. It turned out the expensive repair wasn’t even necessary, and STX handled it quickly and professionally. Honest, efficient, and highly recommended!

    STX were great! (its within ONYX which confused me when I got there, no biggy, just for anyone else reading it). I happened to be arriving when a guy must have been starting their shift, super helpful and got me to the right person. On the way in they even took the time to show my son the Lambo they had, this type of service is so nice to receive. The young guy we spotted fitting the wheels later on, thank you! In for a Stage 1 remap, all done in 30 minutes, and car drives brilliantly and exceeded expectations. Also at a great price as well. All staff I met were super nice and helpful. Credit to you guys! I will definitely be choose these guys going forward! Highly recommend.

    Went to remap my GLE 250d and the whole process was smooth from start to finish. Super responsive, and had the job done quickly with zero hassle. The results are brilliant , noticeable power gains straight away and smoother drive overall. Would highly recommend them to anyone looking for a quality remap with excellent customer service!
