hi audiforum

i have a stockaudi a3 1.8T AGU.

i had it on a dyno the other day and it only had 139whp and 186nm.
when i am accelerating it somtimes 'holds back' or 'jumping' with the engine performances. like the boost pressure is not stable. but only a little.
no DTC with vagcom.
witch sensors could affect this? or what should i do to locate the problem?

sorry about my english. i am danish.
