What happend to my bov?

[TSiWarrior]

When I rev the engine or shift etc etc I can never hear my bov, even when i've got the hood open. I've seen the boost go past 15psi then when I let off not even a slight psst. I understand it will be quite but there is absolutely nothing, ideas?

Check for boost leaks.

1. You can't build much boost, if any, free-revving it.

2. I see you have listed custom dump which I assume is a o2 external dump, could be the reason why you can't hear the blow off.
