First question: Is the engine all stock (cams, muffler, ignition, etc) If so, there will be much difference from stock to 0.9bar of boost. From 0.9 to 1.0bar it's only little due the limitations of the package. On the other side, if not track used, 1.0bar will be only little if any risk at all.

Spring itself are different from each source sometimes, named as 0.9 but 1.0 in real world, 1.0 are 1.0, etc... Search for boost in general here and you will find a lot of info.

You're in France, so here is a source:
