Turns out my rough idle was due to a boost leak...

one of those small plastic Y valves somewhere had a crack in it. Much cheaper than the new temp sensor I thought I was going to have to buy. Also got my strut bearings replaced. Initial word on the harsh vibration at 2700rpm is that it's due to "exhaust harmonics." They suggested that maybe fabbing up another hanger or a strap hanger might solve it. I was convinced that it was coming from the driver's side of the engine bay and asked them to put it back up and check some more. I work 14 hours tomorrow, so no car until at least Wednesday.

I have similar vibes...I just put it down to the larger exhaust

and stiffer motor mounts...
Stage 3 kits sure show you where the failings in the motor will be real quick

Replaced some of those smaller hoses as well with silicone ones.

It seems there is a small amount of oil getting through the turbo which is accelerating the demise of the rubber.
Not looking forward to big turbo #3.
