ummmm.... having traction control on makes my dart feel way different when it comes to throttle response and shift feel. So I always drive with it off. Just made it habbit when getting in the car, but I am a very ritualistic person so that stuff comes easy for me. lolUnless you want a little old style driving feel and also want to take off faster when you dump the clutch, leave it on. Plus, it's annoying to turn it off every time you turn the car on.
