How much boost is the stock 951 engine supposed to handle? (Stock is 0.7bar but what can it safely take)

Remember that the guage is absolute pressure, not boost pressure, so if the guage in the dash is at the "1" marking, then there's zero boost, that's atmospheric pressure.
Typically a chipped car will run around 15 PSI, which would be right about at the "2" bar mark on the guage (atmospheric pressure, which is 1 bar, plus one bar of boost equals 2 bar of absolute pressure).
