it could be faulty n75 valve, and what happens it spikes/boosts harder than it should too early then drops the boost to where it should be (at the revs it is at) so it appears your loosing power but your not, your actually overboosting   :shocked:

get someone with vagcom to log group 114 or 115 (i think) to see actual vs pressered boost pressures to see what is going on

Speak to VW and see if you can get coilpacks under the campaign change.
