si, yea it was a lot more distinct after though obviously it got louder/higher pitch when remapped. the tip and induction kit make it noticeable though as the airbox acts as a sound baffle, i never used the std airbox with it so this is probably why so many people moan about the lack of noise, the induction kit is just a bit of gauze or sponge which is direct through to the dv so hasnt got the barriers that the airbox provides.
