I was wondering after i installed my JWT POP Charger a sucking sound(like sucking a straw but louder) coming from the intake. Its not the normal sound of sucking in air after u lay on the throttle but all the time. I was wondering if this was normal? thanks.

 

It's normal. Mine does it all the time.

 

Sounds fine to me. But just for the heck of it check the connection and make sure it is tight.
