I was concerned about exactly this. The manual has a step-by-step flow chart that requires only techstream. Note the enabling conditions. Also, the Subie TSB does not mention shimming. There are different fault codes for that.
There is one other possibility that hasn't been discussed here. The manual does mention the VVT filters possibly being clogged. I doubt that is your issue but it's worth considering. When everything is working, (codes cleared) does your bank-1 intake seem to respond more slowly than the others?
Graphs of the logs like @
ermax suggested would show this.
