Is the stock boost gauge a measured or calculated value?

If measured, where is the sensor located?

How much boost should I expect to see on the stock gauge at 3500 rpm? At 6k rpm?

Since no one has answered, I'll take a stab at it. If you mean is it a mechanical gauge or an electronic one, it is surely electronic as was the ZR1 gauge. As the owners manual says, the gauge resets the zero point to whatever the ambient air pressure is when the car is started. Regarding readings, I assume you are asking what it reads at wide open throttle -- I don't look at the dash then, frankly, so someone else will have to chime in.

Here's a youtube video link that shows a preproduction gauge at rpm:
