M1100, wierd turbo noise?

[Bendy]

I was out in Blue Sky, BC for four days. I have a boondocker 2.0, BRV, boost tubes, intake elbow, cold air intake (pod) and TD 3" exhaust. At low RPM the turbo starts to squawk. Like someone squealing the tires on their vehicle. I feather the throttle and put it to the bar and its gone? Any idea. Is this engine going to eat the turbo? Thats was 18lbs and half premium and half 111 race fuel set to 18 at 3000 ft and rode up to 7000. It did it at both elevations? F#@KING pulls awesome though!

Your primary is probably not letting go of your belt all the way (binding). Does it more when hot and either coming to a stop or idling. Take a wiff down by your belt when you have heard the squeal and I bet you smell belt.

Sounds like its coming from the intake though?

I don't think its the belt, but it could be. I personally think its the EVO BRV? Gonna go through the sled and check everything over.

I got the same set up as u and I had to change the shim in my secondary my belt was making noises on me. I shimmed my waste gate and am running 24 pounds of boost.

What shim...

did you use? Was it in the tool kit? Thicker, thinner? It goes on the cap? Please explain.
