The latter is mapped so we can go thru the smog test without problems, the chip often have to be removed before the test.

We're doing the same thing here. However GM is releasing an upgrade kit for the Solstice GXP that uses this exact sensor, we however had no clue what the rating of it was. We were trying to find out if the new sensor was a higher BAR rating than the old one so tuners could then increase the boost even higher than the old one supported.

I finally found the information I was looking for. The stock sensor is 2.7 BAR (25 PSI) and the new sensor (the one from the 1.9L 16V JTDM) is 3 BAR (29.5 PSI). So now with this new sensor we can reliably push an even higher boost value through the car.
