I've searched all over the place and can't find a specific answer or discussion about boost gauge vac sources for the MSPNP. I think I can run a tee off the line that came with my MSPNP and run one line to the gauge, and one to the MS Map Sensor, is this accurate? Or do I need to run the line from the gauge inside the cabin directly back to the intake manifold.

 

It is usually not a good idea to share the MAP signal with anything. You want it as clean/accurate as possible.

 

Nah, it'll be fine. A boost gauge isn't actually passing any flow- it's not gonna interfere. I've got a single 1/8" line coming through the firewall, feeding a boost/vac gauge and two MAP sensors. No problems.

 

OK,

Thanks
