Whistle at turbo.
 

I have a 2006 f250 with 6.0. Have installed EGR delete and SCT programmer. I have a loud whistle coming from turbo area. IT only whistles when your foot is on throttle but stop around 2000 RPM. ANy ideas?

turbo exhaust leak could be the cause.

From the down pipe?

is it more of a whine or like a whistle could be your turbo bearing or could be the y pipe wich is extremely common on the 6.0's

Checked bearing in turbo it seems fine..

exhaust leak anywhere on the up pipes or a loose egr block off plate

Found no exhaust leaks or EGR plate loose.. Did find small leak in pipe going from turbo to air cooler.

the cac hose can cause a bit of noise if it has a leak!

Ok thanks.. I'm going to drop it off in the morning to have it looked at..
