tuning issues

[HermaN]

Hey HermaN,

We're talking 2 different things here. Yes, BOV has to go back post AFM. PCV goes back to manifold in the std configuration but lots of guys put catch cans on them to avoid having oily air ingested back into engine.

Ah, right, see what your sayng now. I mis-interpreted what you wrote first time.

i got my car out today and recorded a small log of the issue with my AF ratio changing when i turn my headlights on. i found that the injection timing is changing the most and the mafs is changing some but not much at all. i have not changed anything yet with the bov or the valve cover vent hose just pulled it out and went to work and did a log when i got to work and the car was warmed up completely. i had a question about a oil catch can, i noticed that catch cans have 2 nipples on them and if i route my valve cover vent to one on the catch can where should i route the other side of the catch can. should i still put a hose on the intake in front of the turbo after the AFM and put it on the other nipple of the catch can? any input would be appreciated.
thanks
