I have searched quite a bit and i am still confused about vaccuum lines. Here's a quick overview of my setup;

Boosted B18B
AFI Street Kit
Tuned on Neptune (chipped OBD-I)
Shooting for around 300HP

What is absolutely necessary for vaccuum routing? Is it possible to run everything bone stock as far as the vac lines? So far all I changed was to put a small K&N filter on the valve cover breather port which used to recycle back to the inlet?


Thanks for any help.
