I am not sure about the difference at WOT (with stg 2 it takes days to build up the courage), but it is definitely a tad quieter when cruising top down at say 80kmh. I am actually rarely able to go WOT just to enjoy the nice racing-car like sound, so in this case I hope to improve the sound especially at "normal" speeds.

It could be because at that speed its simply an "easier" job for the engine with the added torque. Isn't it so that with the added boost, more of the energy is being "recycled" which means it will be more quiet? I mean if you were running a turbo with zero boost, wouldn't it start to sound almost like a N/A engine?
