I figure if it did anything it would gunk it up worse.
I used to have to clean the electric EGRs, and throttle bodies, of my Saturn s series annually. They burned some motor oil. Now, we know motor oil isn't exactly TCW3, as the 2 stroke is meant to be burnt, but JMO don't expect miracles.
Part of my inspiration for finding BITOG was finding less volatile oil that wouldn't gunk up my system as much.
