I purchased a second-hand car in the last month which had been to Emerald 5 years ago (!) for mapping/tuning work. I reached out to Emerald just on the off chance they'd remember the car as I had some questions about the car and the map on it's Emerald K6+ ECU and everyone at Emerald has been amazingly helpful. Karl and Dave have spent a not insignificant amount of time on email/phone/teamviewer with me to walk through the queries I had and helping me to resolve some issues. Absolutely fantastic service! 10/10
