If you're ready to go beyond the first step of boost testing you might take look at this tool. With this throttle body block-off plate and hose plugs, you can pressurize the hoses and hardware under the intake (with the intake manifold removed). That means you can see exactly where the leaks are and fix them on the fly. If you have suspected your Idle Control Valve (ICV), venturi or any of the hidden hose connections this kit can help you confirm the problem and deal with it.
For more information on boost testing,see "951 Boost Testing." It's on the right column of this page.
Note: to conduct the first step in boost testing and to use this tool, you will need either the Copper Cap Adapter (aka Boost Test Adapter) or the Intake Test Adapter.
