Do intake/exhaust mods require a computer reset?

[Chewy]

I just had Borla headers, Corsa Touring exhaust, and an Airaid drop in filter replacement added to my H2. I've seen some info that says you need to disconnect the battery briefly to reset the computer so it can "learn" the new setup. The Corsa install manual says nothing about it.

Is this really required? If so, what would the effect be on performance, mileage, etc?

Thanks
