The FMIC liberates a lot of DV noise mate, as you then have an induction kit and a loss of the airbox and associated gubbins (love the technical description ) that mutes the noise normally.

There is some compressor stall in the second "dump" too. This can be achieved by running without a dumpvalve, as I am, but not all turbos are amenable to it.

I find that if i am stood in front of some one then i go in to panto mode, waving my arms and giving verbal descriptions, but as i am typing i find it difficult to explain my self.

the sound i am really for is the sound that if you were to say the word "coooow"

like in that video belowe. look from 1min 50 sec on. you will see and hear what i am talking about.
