exhaust leak either at the manifold to head or manifold to turbo location... torque down the bolts and should be good to go...
 
Check if all your exhaust manifold nuts are tight. and then your exhaust to turbo and downpipe to turbo.
I had my manifold nuts get loose and i had an annoying scream/whistle/chirping sound

Just put cts ko4 turbo on with manifold. When i first start the car the turbo screams for about 30 seconds then goes away. The stock turbo used to do the same thing. Any input wat this might be?
turbo screaming? are you sure its not a belts bro?
 
Re: (sleeply337)

I agree with sleeply. Is it only during cold starts? If it is...it's the SAI system doing what its supposed to do. Don't think it's a turbo problem.
