I would pay just for the whine itself!!!!!!!
But anyway just figured it out! Pulled a twin screw from the shelf and turned it over. Very tight and "firm"rotors meshing together. Go out to my car ...spins free like there is no load. So when engine is at idle the rotors are bouncing off each other so to speak ....and there is your noise. The Mustang blower has very tight "teflon" coated tip rotors and is a tight clearance so no noise but a whine when running. Hope this helps because it answered my question about the rattle.

It can be done with Star. Just checked a Photo as i was changing my intake cooling fluid before winter.
Its the actuator called "M16/7". "M16/6" is the throttle flap.

And thanks for that pic. Just to get this straight, the "Stellglied umluftklappe" is the bypass valve? I really wish I could have kept up with my German language. I lived there for 4 years as a young child and was learning it at school.

Denroll you just mentioned EXACTLY what I have suspected. The timing on the bypass valve opening and closing for shifts is mis-timed. I feel like it opens a little late and closes late as well. There is a slight surge right when shift is initiated, but then it falls on its face (AFR drops into the 11s) and then picks back up (AFR jumps back to 14s). The only thing I haven't logged with all this is boost.
If boost stays on at the start of shifts and drops during the rest of the shift and during the lag period, my hypothesis is correct. The bypass valve timing is off on shifts

Yes, I had mentioned it in another thread or two (there's so many threads now!). Whenever I was driving at grandma speeds, like pulling away from a stop sign, I would get this dip in power right after shifting. Jerry and I went back and forth with several different variants of the tune to get it taken care of. It wasn't easy because my data logs showed nothing out of the ordinary.

Regarding the Picture. Yes "Stellglied Umluftklappe" is the bypass valve.
Hehe nice you learned german, but i can tell you "Stellglied Umluftklappe" are not some ordinary german words. They are rather complex. I bet 9.5 out of 10 german people would not know what that thing described by the term, actually is. "Stellglied" is "actuator" in english, which is strange beacause in germany we also say "Aktuator" to it, i guess "Stellglied" is the super formal german "Daimler speak" word for it hahahaha. And "Umluftklappe" is also strange to me. Directly translated it would mean something like "Recirculation-(Air-)Flap"

The OP mentioned that it was because of timing, not the flap? Or did i got that wrong.

No real issues as of yet. I am having one weird thing thats going on but im not sure what the deal is. The car will pull like a train sometimes and sometimes i can feel a significant drop in power. Im monitoring the temps and they can be exactly the same when this happens so im fairly sure its not a heat soak problem. I was going to ask eurocharged what they though about this but havent yet. Other then that i have done some 3 hour drives in it without any problems.

No i havent been watching those but i will start watching the timing now. I just started noticing it here recently, so im not sure how often its doing it. Seems like when i have somebody riding with me is when it does it

Ok i believe i got it figured out and im retarded. I swapped back to the stock intake system and the car has picked up a ****load of power, so im guessing the filters i used on my custom intake are way to small. My intake temps also have seemed to have dropped by almost 10 degree's...
I didnt really think about this as i did the intake and pulley and split cooling all at the same time.
