im wondering what this hissing is from under my hood, its really no concern but i was wondering if yall hear the same thing. it all started on some weekend project. i took the 2ndaries out of the TB and installed an intake, do you think it could be the intake sucking so much air, or the shafts still inside the TB with air passing over them?

Mine did this a week or two ago. In my case it was the Intercooler pipe had come loose. Might want to check that just in case

 

its your intake hissing...that's all nothing to worry about...if you start her up and look under the hood you'll hear where its coming from
