Should I get rid of one BOV?

[604_R32]

Why do I have an HKS BOV and the stock recirc valve still on there? should I remove it or what, the previous owner said he just got his friend to do it, so I do not know why its on there. Whats the best setup for it. And sorry for the stupid question.

From the pic it look like a rb20det. So odds are you have the stock one so your MAF sensor works and the second one for sound. That's the only reason I can see for two on a single turbo. So if it sounds sick and you like it keep both of you want a cool sound but not as loud take the a/m one and put it where the stock is but recirc it like stock and block the second hole. Just my opinion.

you can block the stock and run atmospheric, but your draw-thru MAF will run like absolute ****.

Also, your threads should really be in 'technical' section.

kthxbi

Sell the aftermarket one and run the stocker. Money in your pocket + OEM quality and driveability for the win.
