Absolutely Brilliant Service – Highly Recommended! After countless attempts to diagnose and repair a fault that left my car refusing to start, I had almost completely given up hope. Then I came across goingslow.co.uk and decided to take a chance on their service. I'm so glad I did! Professional, knowledgeable, genuine and incredibly efficient, with a remarkably quick turnaround. They went above and beyond to make sure everything went smoothly. And most importantly of all… MY CAR WORKS AGAIN! It's rare to come across a business that combines excellent technical knowledge with such fantastic customer service. If you're experiencing ECU or immobiliser problems, I wouldn't hesitate to recommend goingslow.co.uk. An absolutely first-class service from start to finish. Thank you!

Bought a Remapped ECU and EGR delete off of Dom at Goingslow.co.uk. It has transformed the car, not only with power and driveability but loads more MPG too! My Octavia has been given a new lease of life! Bought an EGR pipe for £16 to get rid of the whole system and it will never clog up again! Thanks again!!

Just wanted to say a big thank you! I am well impressed the ECU arrived so quick after ordering Friday evening. Fitted it today (arrived on the Sunday) and took it for a test drive and it is absolutely night and day, what a difference, absolutely delighted.

Dom comes highly recommended, I am a trade buyer and always give clear instruction as to what I want done, this aside I have always had excellent service and some of my modified ecus have racked up a lot of miles, very fast turn around and no stupid postage charges, A1 service in my opinion.

Simply perfect, reliable and understanding. Everything as advertised. I hope to do business with you again. Paolo

Great service ecu works perfect different car in my eyes and royal mail send it fast to
