IMO Cutting is no problem; whereas boosting is.
That is to say even a paltry 1 dB boost demands 33.33% more power. For example, you find a 1dB dip at 30Hz in your room and at that frequency + master volume + sub trim level in the avr if your 1000 watts subwoofer amplifier is applying 900 watts during an explosion in a movie; you will require 297 more watts to fill that dip by a mere 1dB boost. So, your sub amp will clearly run out of steam playing back that frequency.
Now this is regardless of the type of PEQ you are using may it be BFD, miniDSP, or any other.
