When full-throttled, the transmission overrides and sends it back to first gear, thus making it a faster launch. I coined it DWP (Dynamic Wheel-spin Prevention).
If do a first gear launch with traction control, the traction control will kick-in and stop the car; and no traction control will cause a burnout or too much wheel-spin. My technique allows for a faster launch without having the factory launch control.

Excellent trick. Tried it on my 135 and I'm not getting any wheelspin at all.
I timed it a few times and I got around 4.1 more or less. Great run and amazing 70-150. Did you remove the gov. lim?
