Outback Sport Help with diagnosing my engine

06 Outback sport, 38K miles, no 'real' mods, did do a snorkusectomy (i know, I know - done before williaty's write up though)

The other day on the highway I had to accelerate quickly and the engine sounded funny, ever since then whenever I'm over ~4.5K rpm it still sounds funny. Hard to goes from the normal Rrrrrrrrrrrr sound to a waaaaaaaaaaaa sound almost like its over revving. Sounds a little raspy, almost like a heat shield is rattling. Checked the shields and poked around but saw nothing obviously loose. Plenty of oil...last changed ~2600 miles ago.

So any guesses? What else should I check?

I do have a tactrix cable - what data would be good to record to determine if my engine is dying?

I'll try to record the sound later and host is somewhere but that usually doesn't help with daignosis.

Thanks in advance for any comments/thoughts.
