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.

Based on your sig for the 30FF boost leak code I'd check your charge pipe connections it's a boost leak and I've had that before, for the 2C7F it's related to your O2 sensors on your DP's you might have installed them improperly or damaged them during the install. I've never seen the 29F3 code so I'd contact terry and see what he says.
All these codes to me say they are hardware related and have nothing to do with the JB4. |

Why are you using map 6??? Anyway just email in to BMS for support if you need it. Not likely anyone here will have any idea what is going on with the car.
