Blow Off Valve

Had a couple of questions about BOV's. I wanted to know what would be the benefits of changing the stock BOV to say a HKS super Sequential BOV?

How would this effect the performance of the turbo and would any other modifications need to be done by installing one of these. I only ask cause I really haven't found any books that explain this very well and I know you guys and gals are the go to people.

There is none, Keep the stock BPV. With an intake it sounds the same. Also 99% of all BOV setups ive seen/heard, they all flutter which will in time ruin your turbo and you will have to replace it.

The Stock Bypass Valve is more than fine.

Thank you all for the info. Definately don't want my balt sounding like emo shit and if the stock bypass valve is more than adequate, it isn't getting change. Thanks very much
