I was driving and out of nowhere I notice my car doesn't pull when i stepped on it so I shifted and the bov didn't make any noise and you can't hear the spool of the turbo but the boost gauge is normal

 

Visually inspect all intake connection points. Perform a boost leak check?

 

Would a boost leak affect the bov

 

Check your intercooler pipe connections maybe??? When I replaced my icp one of the couplers blew off, you would know if this happened as it makes a lot of noise. If you had a large leak though it might prevent the bpv from making any noise.

When my coupler blew I lost a lot of power ( I would guess 80% )
