P0137 is bank 1/front O2 sensor. Check it.
Check your connection to your boost gauge and make sure it's not leaking.

also if you hit boost spike (Which can be over 1.6 bar) you will get full/boost cut

Sounds like the o2 sim is wired incorrectly.


The overboost code comes on after you fuel cut multiple times within a certain time interval.
