Blow off valve

Been reading about installing a blow off valve because the stock design uses a blank plate and not releasing the pressure is bad on the turbo.

1.why would an oem hand build an engine that is designed for failure according to how others view the blank plate?
2. is a blow off valve going to increase the life of the turbo , stock or with minor mods,etc. piggy back tune..
3.if a blow off valve is suggested, what brands are the best bang for money?

hoping to hear some thoughts.looking to lightly mod my 2015 with piggy back tune..

Thanks yall

Typically either a recycle system (not actually blanked off) or blowoff type design scheme. Some people like the sound of a blowoff, some don't.

yeah i get its either recirculated or blow off style. aside from the sound, i guess i am asking who can confirm the 2015 gla is blanked or recirculated. if truly blanked off, is the turbo getting compressor surge, hence people saying to get a bov
