Er, what is N A engine?
Yeah this 'misfiring' system does perform as you said but the
downside is that it wears out the turbocharger pretty fast. Even
more so if you abuse the ALS.
Oh and depending on who you talk to, some people would regard this
ALS as actually misfiring since that is what is happening. The
thing is that it is a controlled and deliberate misfire so some
would regard it as part of the system. Best is to call it 'Bang
Bang'.
