Blow off without being under a load?

actually you dont need to be building boost for your bov to open.
If you have the right spring/adjusted correctly, it should open up anytime the throttle plate closes at a lower vacuum than idle. load does not equal boost!
you wont get the woosh sound though unless there is a large vacuum difference or in boost.

If you want you're blow off valve to do what it does, relieve pressure from the charge system, YOU HAVE TO BUILD BOOST IN THE FIRST PLACE. There is no "blow off" without boost pressure PERIOD.

LOL Rev your motor to like 5grand or something you mite get a little whoosh action. I remember those days haha. My S13 blew my girls skirt up once when I was on the dyno. She was standing kinda close to the front of the car watching the manifold turn red. That was pretty cool!! Gotta love HKS
