How was that log taken? Vag-Com?
That is ECUx... The vacuum is OK for you, but it could be considered low as well... People will generally say 19-21 is acceptable. But 21 is solid. Know what I mean?

Do you have access to VAG? Log block 118 and see requested versus actual. It wont look pretty like my graph, but you could work something out. Just really have to compare the two numbers and hope they are similar.
