Whooshing sound...?

Alright, I bought a ty not to long ago and I don't remember it making a loud whooshing sound when I let off the gas. Recently I have been driving around and everytime I give it gas and let off it makes a loud whooshing sound depending on how much I'm on it. It kind of sounds like I have a blow off valve, but I don't everything is pretty much stock. It sounds like it's coming through the vents inside the vehicle. The ty is running great and everything. I'm just curious as to what it could be and don't want to be ruining something. When the hood is open and I give it gas manually with my fingers on the TB, after it gets revved it sounds like its coming from the k&n air filter? Is this normal?

Yeah, it's normal, it's even more noticable with the k&n. When you let off the gas while in boost the spooled up air has to go somewhere, so it goes back the way it came from, back through the turbo and through the k&n filter.

That is the sound of the left over boost going back through your turbo and out through you fliter. Kinda cool sound I think, but definatlly not good for a turbo. Its like that on all trucks. If you have a stock turbo I wouldnt worry too much about it. If you have a pricier one or a bb one I would say get a blow off.

Alright. That's good to hear. I guess I didn't notice it when I first bought it because I was staying out of the boost a lot. Thanks :tup:

Make sure the intercooler is tight to the throttle body, my sy got louder one day and that was a little loose.

I thought it could be a boost leak so I inspected it and saw nothing loose or anything so I took it out to a long flat road and floored it and the boost gauge went up to about 15 pounds. I think everything is alright, but I will check the manifold. Thanks
