FB, still curious on the answer to your question. Could you enlighten us?
What could both scenarios be?

More pronounced as revs are rising = ?

More pronounced as revs are on downrev/decreasing = ?

reason I ask is that OP has one issue (rising RPM rattle / noise) I have the other (vibration on downrev at 2000 to 1800).
Cleaning ICV (and MAF/DISA while they were out) cured most of my vibration on the downrev...70%.
