The factory limits are 0.8bar overboost and this immediately drops to 0.6bar
This means your car is running more boost than normal. The code you are getting is just verifying this.
You will need to adjust the nuts on the actuator rod to lower the boost to the correct values. Do this by adjusting the nuts so that less threaded rod is exposed at the battery end i.e. you are moving rod to the drivers side.
Why is 113 not showing ?? The boost is probably within the limits of the overboost i.e. doesnt exceed 0.9 bar which the ECU will allow for a short period (boost gauges are pretty common to read slightly wrongly)
Its the fact it is holding this all the way thru the rev range.
