A few questions before it goes to the tuner..

What does the screw on top of the BOV do and how do you make adjustments. Screw it in it does what..? Screw it out it does what..?

The manual boost controller also come with a little cube -shaped-3-way valve that I dont know what to do with.. One opening blows right through and the other has resistance.

Finally, why does it take soo long to spool up? (or it that the ultimate question) it doesnt start making ANY boost until about 3000 prm. I'm installing a lighter flywheel hoping that will help. I only ask that because my STI spools up and has good power rather quickly. Turbo too big? its a T3/T04E 54 trim 48 AR

Thanks for any help.
