If stock unison ring is ss then why and how does it rust? Also had housing replaced after unison cleaning, due to truck sitting. What is normal vgt duty cycle% and how do you know when to clean?
Unison ring out of a Duramax?
I had a Ford mechanic tell me that the stainless unison ring out of a duramax will resolve the turbo issues with the VGT PSD turbo. I searched around an couldn't find anything. Has anyone else heard of this.
Thanks
Thanks
