the low pitch turbo whine.

There is "No Leak" here buddy, how do you figure?
The low pitch whine is common at engine rotation you are commanding. You are operating at turbo compressor upper limits compression rates.....

Ahh ok this is good to know! I thought it was a boost leak or failing turbo

Oh yeah mine makes the same sound. One of my buddies said that means my turbos goin out. Had me scared for a minute.

Yea I thought my turbos were going out too, but just yesterday I ran a 392 Scat Pack Challenger from a roll on the highway from 60 to 130 and it was dead even.
Then ran into another 392 Scat Pack Challeger, 70-120, same results; both were autos

You ran a Scat Pack on a roll and kept up...?

What are you running? Tune, turbos, etc...

I just have the JB stage 1 on my F10 550i. Yes, it was 2 different Scat Pack Challengers from a roll, dead even from 60-130 and 70-120

Lol, saw your username and thought you had a 535. Nevermind, that makes complete sense now.
