It's more noticable with DCT cars....I notice it on mine between about 1800-2300rpm.

Once the PE has sooted up a bit, it will reduce a bit, but, won't disappear entirely.
I found the vibration in the rear and got rid of it by hitting around back there. Real exact science there. Haha. But the resonance is obviously still there as you both mention. I don't mind it so long as it doesn't cause rattles in the interior.
