I had a tune only 2018 3.5L eco and never heard the blow off valve noise (whoosh) when letting off after accelerating ever. On my 2021 I can hear it when I accelerate pretty hard in first gear and let off. It almost sounds like the VTA mod but I haven't done it. Anyone else ?

Your 2021 3.5 EB is 100% bone stock and you hear the BOV ? Had an 2011 and now a 2019 3.5 EB, and never heard it. Waiting my 2021 3.5 EB. Will can tell you when I will have it... Maybe it's ok with the new 2021 3.5 EB. That engine are retune from the gen2.

I could hear it a little on my 2015. Nothing major, but if you let off the gas at the right time after a hard acceleration you could definitely hear it a little. Seems to be about the same on my new PowerBoost. With an intake you could hear it way more.

Yes, bone stock 21 and get on the gas and let off in 1st gear and hear the BOV. It's not nearly as loud as the VTA mod but very noticeable. I'm just hoping its normal and I don't have a loose fitting/ hose. My 18 was a gen 2 and silent, not sure what they changed on the 21 3.5L.

My Stock 2013 EB I could hear the BOV only under hard accel with sudden throttle let off. Otherwise it was pretty quiet. Of course I could always hear the turbos.

I do a lot of hard acceleration, so probably why I heard it so often in my 2011!:cool:
