The founder of Renntech is a former AMG engineer, and works closely with both Mercedes-Benz and Mercedes-AMG in Europe. From personal experience, I would highly recommend them. The improvements in performance and driving enjoyment are massive. The new Hand Held Tuners are a snap to install and avoid having to open the ECU. The Renntech tunes are placed deep within the coding and are practically impossible to detect. I am not sure about Eurocharged based upon a lack of familiarity. But being as though the Renntech founder worked for AMG, you do the math.
