Maybe the VVEL was throwing the ECU off.. interesting... lol my downshifts rarely end up near 4k

Had to bring this back alive. After driving this car for over a year, I notice it a lot more, and have the ability to recreate it. Anytime I am on a long on/off ramp from a highway, and have a good speed going, and lift off the gas (to hopefully let the car decelerate), the car maintains the speed. Being close to the edge of comfort, it does make me a little nervous, as it is close to the edge of a slipping (and I am prepared to countersteer). So there are 2 inputs, good amount of steering input, and g-forces - it is either condition (or a combo of them) that creates this problem. Anyone else out there have this issue and have you had more time to diagnose it? I am at the point now that I am going to test it around my dealership, so that when I take it in (in the next week or 2) I can show them. I would suspect those that do DEs would feel this (if it was common), on long sweeping turns (which is the only time I feel it). I also notice that it will start to decelerate once the long sweeping turn straightens out (less g force and steering input), or I slightly touch the brakes. It's actually much easier to recognize it since I have installed the FI exhaust as you don't get the decel gurgle until it goes away.

Any others? After all of these Toyota issues, I wonder if Nissan has something similar; these electronic gas pedals concern me.

Why would you expect the car to significantly slow down just by lifting off the gas, especially if you are going at speed into a turn?

I don't expect it to significantly slow down, but I do expect it, due to friction, to not maintain speed, as anyone should. Cars won't maintain speed, if you don't have an input like fuel.
