I put the dp on a few months ago with no problems at all. About 3 months ago this whining sound (can be heard over 3,000 rpm) has been driving me crazy. I took it to my mechanic where they said nothing was wrong. I took it to Bmw 2 weeks ago where they said the sound is coming from the dp and that nothing was wrong. I am losing no boost, no engine lights, no loss of power.

I don't think is is a normal occurrence on cars with a catless dp. The screening is worse when I code boot mod onto the car. When I drive at slower speed I can here the turbos spooling a lot louder, but when I gas it it just screams (like a little girl)

From what I have been hearing it should be the turbos, but I have a feeling it may be something else.

I will add vids below

If anyone has any idea what it could be please let me know! I am going crazy with this sound
Sounds like ur stock DV took a dump, Time to replace that shit. doesn't sound like a boost leak to me.
