Run boost gauge from ECU MAP?

Hey everybody. I tried to search for this but I couldn't find anything on here (or on msextra).
Just curious if it is possible to run a digital boost gauge based on the MAP being read by the ECU. I'd assume you could just program an output in tunerstudio to send a voltage signal based on what the gauge expects to see from its sensor, but I may be totally wrong.
Reasons:
- only one vacuum line
- consistent pressure between gauge and ECU
Is anybody doing this?

I have it teed off the MAP sensor line. I use a gauge because I have an adjustable EBC. And I have occasionally been happy to have it for troubleshooting (coupler blew off or wastegate not shutting completely). I at least knew why the car was behaving strangely and that I could continue back to the paddock rather than worrying about the engine.
I often adjust to run lower boost on the track to preserve the car so a gauge and an adjustment dial suit my needs.
