2022 2.7 2wd chirping/whistling sound

[TSCook]

Has anyone experience a chirping or whistling sound from their 2.7 when accelerating and the turbos kick in. I only notice it primarily at lower speeds, especially when I go from a completely stop. Doesn’t seem to happen if I’m maintaining speed or at higher speeds. I was also able to duplicate the sound when the truck was in neutral and I rev the engine in the attached video. Truck only has 17,000 miles and CDF drum was replaced a few months ago. Thanks for anyone that can help before I take it into ford.

Sounds like a boost leak to me. I would take it back to the dealer that performed the CDF drum work.

Can you share details on how you got them to replace CDF drum? What were the symptoms or problems you were having?

While driving and coming to a stop I would get a noticeable clunk sound coming to a stop. Also would shift hard at times but the clunking was what I brought it in for.

Maybe it is time for me to bring mine in. I get the clunk coming to a stop and really hard downshifts with audible bangs.
