I'm not the guy to ask about ideal AFr's under various conditions - I'm a bit of a turbo newbie myself - but have had to strip virtually most components off my car just to sort out a heap of issues, and start from scratch. So have read and asked heaps on this board. The idle AFR is not really the critical one - when under load (boost) they have a tendency to lean out - so these seem to be the more critical numbers.
My beast is going on the track so most of it's life will be at WOT or hard on brakes.
But there are a number of very detailed threads on AFR's on this board.
Suggest you search, or ask.
I had to reset my injectors because I pulled my fuel head apart - looking for problems.
Oddly, I have 3 CIS manuals, and none of them detail this proceedure.
While you are in there - check the injector patterns for nice even cones of spray.
If they are not - you need to do something with that injector - clean or replace.
