Also, VDC will brake for you when wheel slip is detected, and it will cut throttle if you continue trying to accelerate during wheel slip. Even if you turn VDC off, the ABLS system will still pulsate the rear brakes when wheel slip is detected, although you can overpower ABLS with throttle.
Lastly, I assume this hesitation is new to you? Because the throttle lag on the stock tune is horrid. A tune will fix that right up if you haven't already. |
Checked the back of the butterfly valve on the throttle body, was nice and shiny, throttle lag isnt new to me, but what im feeling isnt that. Basically what happens is this: cruising along on freeway doing 60, pin the throttle to the floor, first second car starts to take off, then the next second or so it feels like the engine cuts power, followed by full power restored all the way to redline. These symptoms are made even worse when vdc is turned on as when i lose that power from the engine for that second the wheel slip light will turn on and sometimes stays on up till about 2000rpm before redline. Tires are new so i know they have plenty of grip
