Yes as if the ECU uses coarse correction ie reduces IAM to less than 1 in order to reduce knock it effectivly reduces ignition timing (hence power) over the entire rpm range even though the problem area may only be in a small rpm band in low rpm area.

the ECU is also quite agressive in removing timing and will often remove double what is needed to supress knock.

You can get a better result, smoother running and more power by tailoring the ignition advance to your fuel rarther than letting the ecu do it.
