Was it a legit bad turbo that created the squeal? I can't think of a single thing that would squeal at exactly 1500 RPM with the turbo since the spool speed can vary a lot at that speed. Was it the wastegate activating? Sounds to me they broke something when replacing the turbo and can't figure out just what they broke.
I know I'm not familiar with the 6.7 turbo, but the 7.3 I had was simple, turbo, wastegate, and not much else, what is different on the 6.7 that could possibly squeal?
