You can't bore out a computer controlled fuel injected engine without re-tuning it. How are you going to custom tune your PCM? And you can't just send your PCM out for a canned tune. It must be done in vehicle. Otherwise, you are wasting time and money.

If you know enough about all that, then why are you here asking questions then? Seems you already know everything.
