0.5-0.6 bar or between 7psi-9psi sounds right on.

I have a APR stage 1 chip and my max boost (according to my guage) is between 15~18psi.

yeah, APR should hit 17ish then taper down to 15... GIAC should hit 17-19 and taper to 15... MTM, not sure, somewhere around that area... if you have access to VAG com you should log block 115 and be sure you're not loosing any boost and the actual meets the specified. or simply ask them if you are not buying it second hand and if you are, ask the previous owner!
