I just had a quick question regarding the placement of the BOV on the FMIC tubing, As i didn't know if someone out there had done some research on our car, I noticed some place the Before the Maf and some place it After the Maf, i realize that if you place the BOV before the MAF it just means that you're blowing off air before the sensor Good bad or indifferent i don't know. Looking for some help on this one...

PRO's and CON's of having the BOV before the MAF or BOV After MAF.

Thank you!

I've never seen anyone with the BOV before the MAF, b/c it wouldn't do what it is supposed to. The BOV is there to release pressure from the intake so you don't get back pressure on the turbo and it saves the engine, and if you use it in recirc it releases the air back in before the turbo but after the MAF so it doesn't read the air twice and run your car rich. So, I would recommend placing it after the MAF and turbo and in recirc.
