Is your aftermarket gauge a quality one and are you satisfied it is accurate?
On the dyno my 0.8 bar spring was not going over 0.8 although on my standard boost gauge, it regularly will show over 0.8 bar.
I have a 0.9 bar spring just in case.

I think that's actually a common occurrence with aftermarket headers. In fact I think you can order GHLs with a re-designed wastegate exhaust circuit (the pipe that runs from the headers that the actual wastgate attaches to) when running one of these "uber turbos" - something like a K27-HFS. I have experienced boost creep with both my B&Bs and now with my OBX headers.
