I wonder if you do indeed have a boost leak. They can be whiny / whistly.
Also... the drop in filter is definitely increasing turbo sound. Could be just that, by itself.
Have you scanned for codes?

I haven't run stage 2 for more than a few days at a time(during the winter). I had the problem before the tune so I want to make sure the car is stable before buying the intercooler and running stage 2 daily.
I changed the drop-in filter to stock to see if that was what's causing the problem. Nothing changed sound wise
Regarding a boost leak, there is no loss of power nor a slow spool from what I can feel. I have also used the boot mod tool for testing (no loss of boost from what I can see)
The check engine light is on due to the oxygen sensors. No other codes have appeared since
