I've remapped and got a carbonio intake, but have no chatter. The turbo is pretty loud though on spool up, and when you let off the power.
Ok, so I don't have an open-cone filter which will obviously make more of an induction noise, but I've heard those that do, and they definitely don't make the noise.
If you want to hear my car to kind of see the kind of noises that it makes then just send me a PM and we'll sort somthing out - you live pretty close to me!
