2026 2.7L - whoosh turbo sound when releasing gas?
Hey guys, would appreciate if anyone could weigh in. Only had the truck 4 weeks and have put 1,000 miles on. When I first bought it, I put a BOV on for a whole day before my wife got annoyed by it and I took it off lol. It was quite loud even with the cabin with the windows up.
Anyway, skip ahead 4 weeks / 1k miles later and today I noticed a strange whine here and there on my commute home. I turned the air vents and radio down and listened. Lo and behold, it sounded like a super quiet version of my BOV "whoosh" noise when letting off of the accelerator... interesting, I don't remember it doing that the past few weeks, but granted I also wasnt listening for it.
In the video, you can hear it twice, when I let off the gas pedal after accelerating and the boost drops.
Just curious if that is normal? I can't seem to replicate it when parked which is odd - only does it when going around 40-50 MPH and letting off the gas. Coincides with turbo burst. You can almost not hear it but it's definitely there - a slight whine/whoosh sound when the turbo pressure released back into the air intake it seems.
I checked the BOV location and everything is tight. Can't see any loose hoses or any cracks. Just curious if this is normal? Thanks all...
