After some thought I have either decided to mount either a digital boost gauge or A/F monitor in place of my current chrono clock. I searched for prior info regarding where to source a location to obtain boost pressure but didnt come up with anything. I need either a diagram or pictures to show me where I can tap into for boost pressure.

 

Try the PLX. Good feedback from other members. No personal experience for me, but it seems to (a) fit, and (b) do the job. good luck.

 

Even PLX will require a tap for boost for the sensor. I am thinking of the same thing... I tapped vacuum at the boost sensor for boost on my old 84, not sure of the best place to grab it on the 997tt.

 

Boost Sensor? Plenum?
