Check measurement block 32 in vcds
this will show you leaks
the values will get zeroed every time you delete dtc's

Ok, i logged some block1 block 31, 32. I had 6% idle Fuel trim and 16% Running fuel trim to begin with, then i reset them and got to 5% idle fuel trim and 6% running fuel trim during logging. I noticed lambda instantly went to 20% when i got into partial throttle/low boost region. i bought new hoses for the PCV system, i think i have another boost leak or vacuum leak that i will track down when i have made a leak tester.
Dont know what is happening with the coolant temp though, still dropping when im on full throttle.
Still got the p0116 p1297 p1602.
