i read somewhere that active sound helps drivers associate the sound with the rev of the engine, assisting in hitting certain notes at shift points along the rev band. "auditory memory" or like "muscle memory," if you will.

NA engines makes it very noticeable to hear the engine and know the revs, and to shift without having to bounce off the rev limiter. FI engines do not have the same crescendo.

this is why bmw, porsche, etc have sound inducted into the speakers of turbo cars.

ASD never bothered me much so keeping it on is fine with me.
