Still having funny sound when I accelerate.

I posted this before, but I guess I'm the first Subaru owner on here to ever experience this: when I accelerate, in gear, the car makes a whining almost buzzing that rises in pitch as I get closer to the floor with the gas. This started a few months ago. It only does it in gear. The best way I can describe it is like making the "Z" sound but rising in pitch.

I don't have $100 to take it to Subaru right now to have them tell me they have no idea what it is. I'm tempted to take it to the family mechanic since Subaru seems really bad at telling what's wrong with Subarus. What I really need them to do, that I don't think they will do, is to come with me for a ride so they can hear it. I'm not sure if I can get a mechanic to actually floor it while on a test drive, and that's when it happens.

What mods, if any, are on the car?

Seems like it might be a vacuum leak. The more pressure as your foot gets closer to the floor, the different the pitch. Check your vacuum lines. Is there a sound when you let off as well? If so, check the BPV line first, and if not, check pre-turbo lines off the turbo inlet first.

This sounds like the most reasonable answer. I would check the turbo inlet as well
