big balance pipe is way over kill from what this member did. On my application I did a 3/4 inch tubing between the BOV which is in addition to the stock balance tube. See my post reply to Spee what happen to PunkZ , local Zer when he lost all his boost from one egr hole becoming un plugged. Before, you go off talking shit and talking abougt not have a "Clue" at least KNOW what you are talking about instead of hear-say and going off of presumptions with no actual evidence. I at least have first hand knowledge unlike you. How big do you think that egr hole is to cause PunkZ to loose ALL, ALL his boost on TD05s. That is one heck of a boost leak.
