I love it.; it really fills that void perfectly. Ultimately I think a 2020 M550i is slightly faster than a Dinan 2019 M550i, but not as big of a difference as the M850i. It seems the shorter low-end gearing for the M850i really makes a big difference in the 0-60 times, something the 2020 M550i does not have. There is a guy in this forum with the 2020 M550i, and granted he's in Florida and I'm in So. Cal, I have better 0-60 times with Dragy.
