Boost guage install

[Flaco1]

Installing my 2.9 whipple and was trying where people with whipple or Roush kits have been hooking to vacuum line for the boost guage. The place that comes mind that I can see the line coming out the back of the intake for the pcv hose. Is there any other places. Thanks

On the lower there should be a plug on the top of the passenger side rear runner.

Is it the one right the pcv hose into the side of the supercharger.

I've used this port and sometimes get erratic readings on the dyno for some reason, curious if others have seen similar issues and if so if they've tapped in somewhere else.

To look into it

You have it right corepwn. Passenger side of the lower manifold, at the back, there is a 1/8" NPT plug. If you remove that, and install an appropriate fitting you can get your boost readings.
