Fender Defender

I have sr20det with my vac at 5 on idle when I'm looking on my boost gauge. My car idles fine and everything. My idle is at 800. It drives fine. Except for the exhaust leaks. I tightened all my couplings today and hoses. My bov T's however are not tightened using a clamp but that wouldnt make me lose so much vac. Can it be my intercooler, bov? Also my fpr doesnt seem to be getting any vac at idle is it supposed to? Like when i press on it theres no vac pressure. I have power fc L detro btw. Engine doesnt sound like before sounds more taptaptaptaptap from under the car which i know are from the exhaust leaks. Iono if I have a built motor cus I never opened it to check lol.

here's a pic of the setup.
I seperated the lines by colors. the green is for the fpr. The red is for bov.



heres a pic of the current setup. All the boost shizz and bov lines were redone by sidewayspfmce as pictured.
