first of i have s14 sr20det blacktop into and s14 chassis with a hks ssq 3 bov and it flutters really badly. sounds cool but i know that could be a problem for the turbo and theres no way to adjust it... what can i do? i also have almost all the vacuum lines ran except for one of the nipples under the throttle body has no line to it. it seems like it should be connected with something but when i plug a line to it it starts to idle low and stall out. where should it go? and when i drive and and go up to around 5k rpm and release gas my idle also drops to about 100???? i know theres tons of people that have this car running perfect but most are asses and just say look at the fsm. ive tried and searched but nothing. also my fpr had a line already connected when i got the motor

link to my other thread since i dont know how to put photos on this website

Your ssqv isn't recurculated is it?? That's why your idle dips like that. And the bottom vacuum line is supposed to go to charcoal canister. I would just cap it and do an idle Relearn. As for the bov issue get a recerc. Fitting or change your maf to blow through.
