Gernot,
Two things come to mind:
1) have you checked the oil level lately? Low oil level will cause the
oilpump to suck air when the oil is sloshed away form the puck-up during
hard maneuvers such as accelleration and cornering.
2) Maybe, and this is a long shot, there is a crack in the sense line
and under acceleration there is something tugging on the plastic tube
which causes the crack to open up enough to allow oil to leak out and
this results in a drop in the oil pressure reading.
The third option is: Its magic!
Good luck on finding the culprit
