The turbo AFM probably has a different spring adjustment so that it also only just barely opens all the way at max revs, even though it flows more air. On this, it's hard to tell, but I'm pretty sure there's still about 3-5 milimeters of travel left, and that's at about 6650 right before the rev limiter.
You should hear the car with the air filter and air box cover removed. After several failed attempts to get a continuous video because the camera would only just barely not fit with the air filter installed and it would push the shutter button while driving, I had to do it with everything taken off. It sounded like I had a glasspack exhaust, except that it wasn't quite that loud, and it was comming from under the hood!
