SandB intake sound

[snowmobiler7c]

I just installed a s and b intake and egt,trans, and boost gauges on my 03 7.3 truck. Under hard acceleration i notice what i guess would be a hissing type noise when trans shifts or when i let up off the gas from a hard acceleration. I imagine that is due to the cold air intake? First time with a cold air on a turbo truck thanks for any input

I put a banks ram air on mine and it does the same thing.

yup its normal. its air "wooshing" (lol) backward through the turbo i think?

Mine sounds like the wast gate is blowing off or something. So i dont know.

Pretty much normal I guess. I started hearing mine after I installed my DIY intake w/ the Amsoil open filter. Freaked my wife out one day she was driving it. She thought, oh sh** I broke his truck. She was afraid to tell me about it until I told her it is normal with my new intake.

HAHA if you have a wicked wheel you are going to hear the turbo even more. but honestly thats just the turbo shooting air back out. normal.. and no you wont hear your wastegate.
