I did search but...

[750F-RM]

Found no answer...

When I select either weight reduction or N/A tune, the game doesn't
warn that these actions are irreversible as it has done before

Are these actions now reversible?

That'd be handy

Thanks in advance for your help

Can be reversed.

Yes they are reversible, and not staged either. You can add just stage 3 or 2 weight reduction or engine tuning just like Turbos.
