Boost over target and Boost under target
So I jus recently put on jb4 G5 and was running on map 5.
When I punch it, it feels like it loses boost then comes back on. Checked my codes that popped up and got: 2CA7 Lambda probe heating in front of catalytic converter 2, function 30FF Boost under target -- possible boost leak 2F0C No Description Found 2F08 Inlet air temperature sensor, signal 3100 low boost mode engaged -- CEL displayed 30FE Boost over target I checked my vacuum lines they all seem to be fine. My stock charge pipe seemed to be fine with no cracks. Here's a couple logs: https://datazap.me/u/micah007/map-5?log=0&data=1-2-4 https://datazap.me/u/micah007/log-15...0&data=1-4 Im fairly new to the n54 life and is trying to learn a lot from it. Would be awesome if you guys can help. Thanks ! |
