JB+ might just be my best bet I guess. Do you feel the diff w ur JB+. Also, with the dial turned up to 100% from its previous position did u feel a diff l. I just believe that the JB+ isn't the safest option but whatever hopefully it'll be fine.

There’s no need to cut into the stock harness of the car even with a JB4.
And yes. There’s definitely a difference. JB+ kinda feels like map 1 of the jb4 (not my words. Words of someone else who did a JB4 upgrade from JB+ on their f30 330i). And JB+ isn’t unsafe per se. Lots of cars running JB+ without any issues. But I’ve read about lots of cars being tuned and having issues. So yes.
