That would end up putting unburnt fuel and air into the exhaust, which
would ignite and probably do some damage, or at least create a lot
of unwanted head in the exhaust system. It's more likely that TC
systems skip fuel delivery to cylinders in a cyclic pattern perhaps
from 1 cylinder every 4 revolutions to 2 cylinders every 2 revolutions
switching which cylinders are skipped to keep temps even. The other
method is to retard the spark a bit, but generally that doesn't cut
much power.
