I was always taught that power made VRS worse. That's been from my first days in the TH-57 (B206) until now. If you can power out of it, then by definition, it wasn't VRS. The only exception, I would think, is if the additional power aggravated the VRS to such an extent that one continued to descend through the bad air and managed to get into better air below.
Even in helos, we were taught to freeze the collective and get forward airspeed.
In the V-22 one rolls nacelles forward, which immediately changes the thrust vector.
Now, the V-22's induced velocity is so high that one has to have a truly sick 2000fpm + on the descent to get VRS. If you have that on short final with less than 40KIAS, your approach is going to end in failure long before encountering VRS.
