Its not so much a hissing sound. It surges 3 or 4 times then it clears up and goes! I would love to replace my turbo with a better unit but right now the time isnt right! I am thinkin about going with the ported turbo housing. I am going to wait and see what is new when i attend SEMA the week after next!!
