Les, you should try some laps with it on, and drive the course as hard as you can. This little car loves to rear end swap because of its short wheelbase. I have had a lot of track time in my day, and have tried both ways with this car, and the fact it does over-ride in the off mode, it is unpredictable, but with it on, it becomes predictable...just try it...if I could take the t/c out of picture all together, I might change my mind, but with it off, and you accellerate out of corner, and it starts to break traction just as you are getting a feel for the corner, and it kicks in, shooting you straight while you are still in drift mode, isn't fun.....
