think you could back it off a little looks like too much with large boost spike now on adj no2 around 2500revs maf airrises very high but iq doesnt increase much at all from no adj or adj 1 , are you fuel limited ? needs a certain qty of fuel to make exhaust gas to spin turbo ?
can you try increasing iq 1-2mm3 and see if boost reaches desired and requires less vnt % to do it .
just a thought.your afr looks around just under 20 sure you could go into 18's or low 19's
