just sayin N55 are not the strongest bmw engines, jb4 add more safety than MHD alone. Custom back end flash are pretty nice. You can manually dial up the boost per rpm via jb4 and log. If you're serious about your logging, 100% sure you'll get most of your engine, with proper monitoring without having exactly MHD requirement mods.
After few pulls and JB4 adjustment , some folks get their car professionally tuned after, and they get marginal gains. Pretty solid DIY safe tuning method, and if OP dont go with a DP, probably cheaper than MHD alone.

2016 X3 N55 M sport. Not looking to do 1/4 drags, just some extra HP for passing power on the hwy. Next mod will be the xhp transmission flash, not happy with the response of the factory setting. Since i already have the latest MHD wifi adapter, should be an easy flash
