In todays video theres an update on the SL63 with the lifter noise complaint. I show a little bit of the process on a 2014 BMW F10 M5 that was getting KW coilovers and a brake service. A CLS 63 (m157 biturbo) with a tune came in for a dyno run so I was able to film two runs. We also did a service A on a W205 C63s with downpipes and a tune, I hope you enjoyed the burbles and I want to note that the revving at the end was the owner. I hope you enjoy!
