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.

I just installed the JB4 on my 2015 M Sport 550i. So far it’s great. Haven’t had much time to tinker with it but the added boost is so much fun to play with even just with the 1st setting. Very happy so far.

It's a must for the G series M550i IMO. With the AWD, you can really have fun and take advantage of the new added power
