I'm running with constant 1,5bar with the overboost up to 1,7bar. I did 10.000 kms with such boost pressure and it's still ok. I examined both turbos last week - their condition was perfect.
If you will take care of your oils (engine, gear box, diff.), spark plugs and filters your turbos and engine shouldn't have any problem with such boost.

Greetings.
