Could be a confusion of definition between measured boost and absolute pressure. Air pressure at sea level is 1bar. Some gages read in absolute which means 1 bar ambient + 1bar boost = 2bar.

Either way please do not use more than a 1.0bar spring, the stock air cooled 930 engines are not designed for it.
