ok i guess that would make a car run better if it doesnt have maf restrictions... i dont think it would be necessary for me yet until i go boost though... havent looked into it yet but idk maybe it would be... lol

its not the restrictions that cause problems. its the way the maf reads air. if you have a bov that vents externally it will never idle right when pulling up to stop lights. runs rich when shifting at any gear. wastes fuel. if you have a vacuum leak or a pipe blow off you are stuck on the side of the road. if a pipe blows off my car i can drive home or anywhere no problems. just like its n/a

^ unless you run blow through.

ohh ok thanks for the info... thats nice to know

blow through setups work but there always tends to be a bit of oil in the intake tract. that oil damages the maf and alters readings over time.
