ExploreJust an update,
I know some of y'all are butthurt about this being a c43 blah blah, but the c63 has had weird issues like this too so it may be relevant.
I took the car into tghe dealer today to tell them about my situation and he tried to tell me that the 4.7s is in perfect conditions, so i told him about the million different launch scenarios ive tried and he agreed to have an appoimtment for me this weekend to look at it. He said there may be a transmission update and that it would be hard to confirm 0-60 times so that should be fun.
