Hi Everyone

I was hoping someone could offer some advice here. I have an '08 S40 D5 and would like to know where the vacuum line from the CBV plugs into the intake? I had the idea of installing a little needle valve in the line so I could get a bit of turbo flutter at low boost, but still retain the operation of the CBV at high boost so that I don't cause any damage to the turbo unit.

Is this ill advised, and if so - why? Would love to hear if anyone else has attempted this. Im sorry if my question seems elementary buy I'm new to Turbo Diesels and dont want to harm my prized possession or land up with a hefty repair bill.

Thanks in advance :)
