no offense. But I'm 100% sure. The easiest way to see I'm right is to go outside in your redline, start the engine, and try it out.
I dont know if you are directing this to what I said, but to clarify see below.
Page 199 of the manual.
Traction Control System - ON
This system limits wheel spin. The system only operates if it senses the rear wheels are spinning to much or are beginning to loose traction. When this happens, the system works the rear brakes and reduces engine power to limit wheel spin.
OFF- The system will not limit wheel spin.
Electronic Stability Control
The ESC system combines, anti-lock brake, traction control and stability control systems and helps the driver maintain DIRECTIONAL control of the vehicle in most driving conditions.
Competetive Driving Mode
This mode allows the driver to have FULL control of the rear wheels while the ESC system helps maintain directional control of the vehicle by selective brake application. When Competetive mode is selected the traction control system will not be operating.
The manual does not clearly cover full off, but if you look at your DIC while holding the button for approx 10 seconds you will see it indicate traction off first then it will indicate ESC off next. Now your in full manual mode. As you said, go turn the car on and check it out. The all off mode is by far, IMHO, the best option for performance driving.
