So I ran again this morning. 2nd gear launch but let it shift by itself. Unlike my gas 335i, the 335d shifts before redline (fortunately!). Same temps, emptied my trunk, and switched from USA diesel to Union 76.
13.1 at 106.1 4.7 0-60, fighting wheel spin.
Still just above the medium setting. Can't believe the fastest time on Dragtimes (by the same guy about 10 times) is around a 13flat. Maybe I be the first to break into 12's on that list.
Very cool. How is it the car is automatically shifting in manual, I thought you had to be in DS mode to do that.
