Your car pulls in, in pulses, which express a bunch of energy as sound, which reflects more easily than you might think, and being as that it's a pressure wave (sound is a pressure wave, remember? Doppler effect, kinetics of sound in water?) most definitely affects your intake and exhaust.

I referred a book earlier, might blow your mind to read it-- intake and exhaust tracts are much more complex than you may think.

Fantastic! Looking forward to seeing the results out of blatant curiousity. Really wish I had access to a dyno where I could run programs, being as this car is TBW...
