HomeTuning TechMercedes CLS550 with VRTuned ECU Flash Gains 8mph in the 1/4 Mile VRTuned.com November 14, 2017 Tuning Tech Not a huge amount of enthusiasts realize just how tuner friendly Mercedes’ engines can be. When you think of performance, you probably don’t think of the CLS550 4Matic, one of Mercedes’ largest cars. One of our recent customers, however, showed us how much performance was gained after they came in for a simple ECU Flash from VRTuned. Before our customer received his VRTune, he was running around a 13 second 1/4 mile which is pretty respectable for such a large car. After the ECU flash, they ran a 12.205 second 1/4 mile at 155.3mph! To put that in perspective: that’s faster than the average Mustang or Camaro. Check out the video below to see just how crazy fast this CLS550 really is! If you have any questions regarding the modifications done to this vehicle, please do not hesitate to contact us.
