Getting vibration from s475 cast wheel turbo. Is this a common thing with the 475/stock? This setup is new just installed and yes I primed the turbo prior to cranking and checked that it got oil while cranking before start. It's bad enough that it rattles the shit out of my dash till I get the rpms up around 760-800ish. Talked with one guy who said it's normal just have tuner bump up idle rpm. Given after I drive for a while it stops at idle but when I let off throttle there is a sweet spot where it vibrates/shudders and again when I throttle and it hits that spot but clears up after. Any input as to if this is normal, what I should check or if something is off would be appreciated as this is my first larger turbo
