In regards to the values above 5000 ppm, this is due to getCO2(). It doesn't limit the values that the sensor thinks it's reading. This includes values below 400ppm.
If you use getCO2(false), it will use the capped versions, but it shouldn't change the scale of the results you are seeing.
Has it been calibrated?
