Have you had any issues? I've used a JB4 of my last 2 BMWs (2014 328i, and a 2016 340i), both with great success.
However, I recently posted in the N63 forum of Burger's website about my concerns. EVERY......SINGLE......OTHER.....POST..... was nothing but people complaining about problems they were having, and I even saw BM back-tracking on a post saying "Well, the nature of the engine makes it very complicated to tune".
Not what I wanted to hear.
I have no doubt it performs better..... how's the reliability and stability of the tuning working out though?? Any CELs? Misfires? Other issues?
