Why use sport and not track?
Track mode seems to implement TM, I can feel it.... In sport mode I am not feeling it if I do a half second accelerator depress. If I "roll" quickly into it from 1,500 RPM brake hold, I am not feeling the motor drop out..... seems like I can in track mode.... like it is controlling the accel for safety or consistancy.....

This is all on an unprepared surface..... on a prepped strip, this may not work as well......

As you can see I have not broke the 3.5 0-60 barrier GM states with this method or any other I have tried, but I have the 1/4 mile time in the bag now.......
