My 2020 Limited max with 34,500 miles has a turbo whistle that I just recently discovered. I say recently because 99% of the time when I jump in the drivers seat...the A/C or heat is running...then the B&O kicks in with tunes and now I'm in my happy place
A few days ago I got in to leave work and it was such a beautiful weather day that I shut down the A/C and B&O completely, rolled down both front windows and slid the roof glass all the way back. We're in a rural community so you can easily find yourself being the only one on the road..... and that's when I heard the turbo(s) climbing up a mild grade the moved the turbo gauge needle about an eighth of an inch into the blue. Turbo sound doesn't bother me at all after owning F250 PSD's...
All Im wondering now is if this is normal or is there something somewhere loosening upstream from the turbos?
Its not anywhere near as loud as the PSD...not even close and I can't determine if its the right or left side...or both.
HAs anyone else heard their turbos singing ?

It's normal to hear the turbos whistling, especially under heavy throttle or right when you get into the spool range (1500-2000 RPM)

I can definitely hear my turbos whistling along with the rattles from the **** wastegate on both sides. Sounds awesome.

Do you really mean awesome, or awful? Just wondering.
I said awesome but being sarcastic.

I just dont like the wastegate rattle, It does quiet down after it adjusts itself after 20 seconds cold start, But it still rattle when u rev the engine after that

I can hear the whistle and the the blow-off valve, even with the windows up. It's just subtle enough to notice when music isn't playing and I LUV IT! Just the pano sunroof rattles that destroy the experience...

I can hear it even with the music on and the kids talking. It doesn’t bother me. If anything I’m just happy my wastegates aren’t rattling.

The springs fix has worked flawlessly for me. They have been on for over a year and 27k miles an no issues other than wastegates that no longer rattle.
