Alright i have a 2.0T for thoose who don't know. Anyways i have a Turbo XS BOV and am venting to atmosphere. Shoul my BOV be closed during idle, my idle seems to be rough. On the directions that came with the BOV it said for it to be open but i think that was if i was using it as a DV. Anyways im a big dummy and need help.
