Default Jb4 problems. N63 - 03-20-2021, 01:27 PM

I just installed my jb4 and ********* on my 2013 x5 50i. N63 engine.

My problem is on the jb4 app, only my boost gauge works. Rpm, afr, coolant.. etc.. don't work. Also will not boost over 10psi on any map. I downloaded all the newest firmware for e70 n63 but nothing changes.
Any help would be great.
