Its expensive
. To get Stage 3 you need to install the Dinan FMIC for the 335i which cost $1500 and have it custom installed like I did:
The 335is has an additional frame behind the M-Bumper that needs to be modified and then the FMIC fits right in perfectly as you can see above. A Dinan dealer, other than BMW, are the only ones that Dinan will alow to do this. Labor on this can range from $400-$700, you cannot do it yourself, Dinan will only cover you if their approved dealer does it.
Since I had the first Stage 3 Boost upgrade that was made for my 335is more than likely you will get the same version I have. The Stage 3 will cost about $2200. I am getting about 360whp and 410wtq enough to take out a 135i w/ JB4 on Map 5 from the dig:
It take about 100-200 miles for the DME to adapt to the new tune.

Now about the wistling sound and loud turbo spooling, I have a video of it will post later, I think its normal as you increase boost. There is no loss of power at all on my end and my charge pipe is fine, which of course I might change later on. Better yet when I have some time I will drop it off to the dealer for them to double check it.
