Default Disturbing rumble

Im a little concerned about a rumble I'm getting from my car
Info:
It occurs from 2400-2600 RPM's
It only occurs in 4th, 5th, and 6th gear under full throttle
I doesnt occur when in neutral and not moving
I havent tried it in stock mode, only in APR 93
It sounds like its coming from the rear of the vehicle
I just had my tires remounted and balanced

Im concerned because it rumbles at a specific RPM and throttle as opposed to a specific speed, and also because thats around the RPM that the turbo spins up.

Any suggestions, similar problems, diagnoses would be greatly appreciated.

Default I have a sound that reverberates at certain RPM and gear

Related to the exhaust from a few people that heard it. Even the tech adviser from Audi heard it also and couldn't be sure what it was but said that it might be exhaust related and he couldn't find anything in their tech database.

It just started happening right after I got my tires mounted and balanced, and its not just a sound

No, valve stems broke from aftermarket caps, so they needed to be replaced

Check to make sure tires are inflated and mounted correctly would be a start.
