Compared to what?

I am rewarded with an immediate increase in power when advancing the
throttle of an IO-360 or O-540; there is no significant delay between
opening the throttle and an increase in power.

But perhaps I was misinterpreting what was said. Of course there is
some delay before a burst-throttle and the engine reaching full power
due to the necessity of accelerating the mass of the moving parts
involved.
