Default JB4 causing engine malfunction codes - 10-13-2020, 08:24 AM

Just installed my jb4 on my 08 535xi. First start was smooth and no error codes so i covered everything back up and decided to take her for a spin. Upon my second start I got a half engine light and when I read the codes i have 2
2ABD- intake pressure sensor
30FF- Boost under target
I was running map 0 so I am not sure what went wrong and my car just felt week upon acceleration and in some cases would redline and not even shift.

How can I fix these codes??
