OK, slight thread drift.
Manufacturer has some published data. Yet, when the manufacturer gets your "thing" they adjust it to a value that is around 7-13% higher value. (This could be voltage, oil pressure, fuel pressure or any other thing) They do this work in their very own service centre and return it to service for you. They do it for a good reason, known to them and many others but it is outside the published data sheet.
What do you do?
A: Leave it alone as they set it up as part of their service work and signed it out
B: Reduce the level to the data sheet despite knowing it is better to have it where the OEM set it.
C: Start adopting the same practise yourself as it makes sense?
D: Ask someone at CASA?
Eddie responds with
In answer to your hypothetical Jaba, contact the OEM and ask questions
Thats a great idea and it was deliberately not an option offered because the OEM knows and tells you that their setting is better than the book and for good reasons.
So……what do you do now (In Australia)?
