1. Overboost switch will typically trip at 1.1 bar.
2. 1.1 bar is a too high to run on non-modified engine and it will shatter the piston rings sooner or later.
3. Even if you have modified CIS to support fueling at that boost, 1.1 bar on 3DLZ is "lots of hot air and little extra power". The fact that boost gauge goes higher doesn't necessarily mean that you have extra power.

Check if wastegate membrane ruptured (by blowing air trough boost line and noticing if it seeps trough).

If you are getting steady 1.1 bar on Autobahn then you either have very stiff spring or there is a malfunction on wastegate side. If you only get spikes to 1.1 bar when shifting then recirculation valve might be stuck.
Thank you for your time,
