Are you asking if you need to tune it? Yes, you do.

A stock, untuned B18B ECU will not have enough fuel for a b20. You might be able to run it temporarily by increasing the fuel pressure, butI can't say for sure because I've never done it before.

No, you will not run lean if it is tuned right. I think I understand what you are asking. The ECU can control larger injectors required with a larger engine so it is not a problem.
