I installed a return spring to help the weak spring on the BBK TB which helped the hanging revs a little bit.
Just quasi-quoting from the Jet...

The BBK throttlebody is not as nice as the Focus Central unit-the FC appears to be billet whereas the BBK is cast and machined. A little too rough, especially in the throat where there is a definite ridge where the machine work ends. I spent a little time blending it in before I started the install. And I can't seem to get more than 8 1/2 psi, but that is most likely due to my Crane cams which I have yet to dial in with adj. cam gears (on my to do list).
