First time taking the beast to the track!
I usually run ms109 in my old e55 but was catless.Do you guys think it's ok to run that on the c63 with stock exhaust?





For what it's worth, my car always puts up its fastest times when I'm lucky enough to be running hot laps at the dragstrip. Usually takes until the 3rd or 4th run in a row without cooling down before it puts up good numbers.

I was there for 2 hours and got 2 passes.both crazy the excat same time 12.20 on both runs.
I'm Happy I have a solid baseline of 12.20 with 2.0 60fts to work with for when I go back.
I can tell u on the way home the car feels peppy and super sharp on the throttle response.
