Is anyone else using one of these... www.boostvalve.com

I just bought one. It looks like you block off the line coming
from the compressor housing. And take the line from the back of the intake
to one of the ports, and the other port goes to the actuator.
Then set the WG rod to low boost, and then turn up with the valve.
Just checking to see if this sounds right.

I wondered about why they want a manifold boost source as opposed to the compressor. I also wondered last year what would happen if you used manifold boost to power the stock wastegate solenoid (with no boost valve). Seems like it would have a laggier response, I dunno.

The boost you make at the compressor isn't going to be what is at the manifold. It depends on your intercooler efficiency, there will be a pressure drop.
Not sure if that is why they do it, but its my guess.

Jim is using one, but not on a Ty or Sy. Let's know how this works out for you.

How exactly do these things work? I guess I don't understand enough about how all this stuff works together to control the wastegate...

Is the Grainger valve/MBC thing the same as the retail Boost Valve? Does it just make the wastegate actuator not see any boost until it exceeds the dialed-in level (set with the screw)? That in turn keeps the waste gate out of the picture until you hit the dialed-in level so you get faster spoolup, right?
