Do these chips simply plug into OBD ? Is mapping an ECU from BM as easy as they make it sound and could I change it back just as easily for smog inspection?
I'm new to modding these cars and want to be able to remove whatever computer performance mod to pass CA smog when needed.
Is this how it works?
Thanks for your patience with these noob questions. Any help is appreciated.

by chip you mean custom tune/OTS tune?
