OK, so maybe this is subjective, but...

It seems like the time rate of change of acceleration (jerk/surge) is greater when acceleration starts at a higher rpm.

This isn't just spool time for the turbo...enthalpy of the exhaust gas...blah blah blah.

What I have noticed is that if I start accelerating at, say, 1500 rpm, the rate of acceleration is lower at 5000 rpm than it is if I start accelerating at 3000 rpm.

Is this an ECU thing? Not clear how it can be measured or if I'm just hallucinating, but I did a bunch of runs and it sure seems like you catch the car napping...
