Can this item help prevent boost creep?

I saw this on the GReddy website...it sounds like a secondary wastegate. Any opinions on this?

It may help prevent excess pressure from being forced into the engine, maybe. But in order to do this, it vents to the atmosphere (if I understand this product correctly). At which time it would not only make an awful noise, but all that once-metered air venting would cause a rich condition. This rich condition may be not as bad as boost creep, but is still not good.

It's a bandaid. Bandaids should be avoided, generally speaking.

sounds like a pop off valve, if you have a spike it releases the pressure into the automosphere. it may stop boost creep, but your turbo will still be overworked i would think.

Stick with a wastegate port (NOTa complete PnP). Cheaper and easier than any other alternatives.
