I 100% agree on the valve movement. Its not much. OEMs full open looks like 30% open to me.
I also totally agree how loud the fake noise is. Its a lot! I was blasting my stereo a few weeks back to some 90's rap. I was probably 75-80% max volume and turned the ASD off with the button. OMG. The musics bass hits sounded SO much cleaner.
I would turn mine off. But I find it way to quiet with it off and only a stock exhaust with valve controller. But man, ASD its really loud and deep!
