Default Yes, the part throttle trim is too lean.
Few things to check is the vac line at the fpr. Also check for any leaks between the maf and turbo.

Check your max maf readings. If they are low you prob have dirty/bad maf!

Very low for a K03 at even a low boost level.

Default You have a bad maf, Devious 1.8t also has a PES Kit
and his maf sensor was also bad. He also had a bad 02 sensor but that was throwing codes.
