Issues with JB4

Hey guys maybe you can help me out. I installed my JB4 today on a n54 135i and its been a shitstorm of issues all day. At first startup the car started good idled fine but my psi wouldnt go past 10. The same on map1,2,3 & 7. The car feels no faster than stock. I even customized map 6 to 14 psi and that caused more issues. My CEL came on and i threw these codes:
29F3 Fuel pressure sensor, electrical
30FF Boost under target -- possible boost leak
2C7F Lambda probe behind catalytic converter 2, trimm control.

My car had no issues before the tune. And also I didnt pass 10psi on map 6.

Here are some runs that I logged. Any help would be appreciated.
