Re: test run and crazy noises
ok, when you let off the throttlebody and close the throttle plate, this creates vacuum inside the intake manifold, not in the charge pipes, where you had the BOV hooked up too. Infact when your accelerating, the charge pipes have pressure in them from the turbo, and closing the throttle plate makes more pressure between the turbo and throttle body. If the BOVs vacuum source is located at the valve cover breather fitting on the charge pipe, it'll never open, infact the pressure will probably hold it shut harder.
Hook the vacuum line up to some vacuum source from the intake manifold and you should be good.

Y I can see the pic better now, the 2 are coolant lines the other is wrong. you need to move the one on the intake pipe to the other side of the throtle body, T off from any other "VAC" line you have there. put your finger on it, if it doesnt suck in your finger then it wrong or you need a new engine
