Yea, the throttle control transition is not always smooth. I have my foot down and steady, and it feels like it is oscillating between throttle position values even though the clutch is fully engaged.

There are other times when I progressively press further down on the pedal I would expect an increase in response, but instead it's either a flat spot or a tease (it rises, but plateaus the rest of the pedal travel as if throttle hit a low ceiling).

I've done some tests where I get the car rolling in 2nd around 1k RPM and then flooring it. When it is "cool," the revs ramp up very quickly. After driving for awhile, it takes forever to ramp up past 4-5k RPM. Pre-VHR engines don't do this. Because of this, sometimes I have a hard time getting the turbos to spool up. In 2nd and 4k, there's no boost as if throttle wasn't opening fully.
