2019 ST with Livernois 91 (mid-level) tune. About 30 deg. air which I'm sure helped. I still don't have a convenient safe place to do a 1/4 so I'm just doing 0-60s. Stock tune was 5.95 0-60.
I did brake-hold to about 2500 rpm and let it go. Trac was off, and I heard multiple tires chirp--that probably had to do with the all-seasons I had on--very hard rubber in the cold. (I just put Hankook WinterCept Evo's on yesterday).
