High pitched sound during the turbo spool after unitronic intake install?

I had a guy at my local shop install the Unitronic CAI for me, and it all looks just how it should be, and it sounds awesome, but there's a noise that sounds not good.

Example of it in this video:

https://www.youtube.com/watch?v=2bS82-2aLhs

What could it be?

Edit: Forgot to mention. I also have the APR Stage 1 tune.

It's part of the sound from the intake?

It's the diverter valve. You can either:

1. Live with it
2. Install a GFB DV+
3. Install the DV Relocation kit
4. Take your chances on a stock rev D DV

Had this noise too, mainly why I traded it for APR.

From what I know, you'll need a diverter valve relocation kit.

I have a revision D diverter valve and it was still present. Not sure even the GFB DV+ would fix it.

aye...

Man I did not anticipate this for some reason despite doing what I thought was enough research.

I unfortunately am not familiar with anything you just said as I'm only basic in my auto knowledge

What's the most practical way to go about it? Option 1 is not an option for me here.

Thanks for your help by the way.

edit:

Is this what I need?

My search-fu failed me, and I hate asking questions because I know I'm never the first.

Thanks for the help.

Try moving the filter back and forth on the intake tube. It is a harmonic, the Mk5 did it all the time with the filter on a stick design.

Exactly.



I did #2 and it solved the noise issue. The Rev D DV is cheaper and I am fairly certain that solves the issue.
