Venting Blow Off Valves - Why Not To Do It

[Bboy_Sparx]

Car You Have: MKIV GTI
Basic Mods: Relevant bits - Stock airbox, TurboXS piston DV
Vent (Yes or No) : NO
Why? I had one before and the exhaust isn't loud enough to warrant the sound IMO. If I had an S15 with a 3" straight through exhaust I might do it, but on my VW, I can't stand the sound of it. Then there's the A/F ratio, and stuff getting lodged in the chamber (<- Ok that is just paranoid haha)

Most importantly, it ruins my music - it sounds like a random high hat.

Why? Did not want CEL, did not want defect notices
Where did you get the information as to why or why not? Mostly the interweb. Also tuning shop.
