Car over boosting with weird symptoms?

What's going on guys

I just had new injectors replaced because of misfires and turbos because of the rattle and having a weird symptom with my car boosting.

The cars boosting almost 19-24 according to my boost gauge and throws 30ff and is showing all sorts of crazy boost spikes. This power is very inconsistent and one point it's reading 5 next 15. In stock map it's okay but still weird spiking and random readings.

I'm thinking boost solenoids so I'm going to replace them and install a new ER CP too with new oring and hopefully issue will be fixed finally.

Who did the work?

Did they code the injectors correctly?

What tune?
Have you updated firmware and maps?

Have you tried resetting adaptations?

There's really so many things it can be, please offer up more details if possible.
