Default M550 JB4 Owners - How do you like your setup? - 02-20-2020, 12:12 PM

For the M550i owners out there with JB4s, curious on hearing your thoughts.

How does your car run? Any quirks? Still smooth during normal driving?

I had a JB4 with my N54 E92 and loved it. But am carefully considering my options before making any modifications to my 2018 M550i.

Appreciate any thoughts or comments.
