Anyone else have some minor vibration through the steering wheel and chassis over around 3 to 4krpm and above? Just got my break in service done and finally floored the pedal. Repeated pulls showed a little bit of vibration which creeps in until I shift. Is this just characteristic of this car or do I have an issue? Not sure what that would be.. motor mounts or something?

They put brand new tires on (unused summers on finally) and it's fine when coasting so it's not balance related.

edit: it's definitely an overboost related vibration. Only occurs on max boost, and doesn't really seem evident when overboost is in cooldown.
