Bov without even going over zero psi?
Is it possible to blow off without even going over zero boost? Mine seems to do that... maybe my boost guage is wrong? I have a greddy electronic boost guage and a dsm bov. But when it does blow off, it is very light.

Exactly - the turbo IS boosting, but it's only "boosting" the piping up to the throttle body. You're driving around at part throttle, so there's a big obstruction at the throttle body, and the pressure in the manifold is still lower than atmospheric, but there's still positive pressure in the piping for the BOV to vent.

thanks for clearing things up for me. Dbman, your the man!
