I am thinking about having my 2016 c63s dyno'd to get a base number before some mods. Is there anything I need to do. Dyno shop told me that they tried to run a dyno on a 2014 c63 and there were too many protective issues and they wren't able to do it.

 

That's because the shop you talked to was too lazy to do so,e research. You have to put the car in dyno mode. There is a video online and referenced here in the forums showing how to put a c63 into dyno mode.

 

Might want to find another shop. The one you described doesn't inspire much confidence.

 

I looked and did a search for it but wasn't able to find it hence the thread.

 

You may have to pull both paddles at the same time while pressing the buttons. It's a bit tricky but works for sure
