I only have 1,600 miles on my 2021 550, but I got a dragy and I am on performance tires in texas. So, I'll have to find a road by my house and try launch control soon.

I’ve owned a lot of fast cars, one quite a bit faster than the 550. The reality is that it’s very rare I want it go wide open from a dead stop. But I get that y’all want what it’s supposed to have. |
I previously had a heads/cammed c6 putting down 500rwhp and 1,000 pounds less than the m550, and the only time I was launching was at the track, which was rare. So, it's not as important to me; but I certainly agree with you and the OP as you want what you thought you were getting when you bought the car.
