What does does punch control actually do?

[crazyjr]

I can only give my experiences with the punch control, I tryed it once, it made the truck more controlable (T4 with a mambamax 4600). But i later forgot i messed with it, I remembered it running better and thought i had demagged the motor, I was updating it and saw it was at 75%, reset it to off and the motor came back. I use the curve for throttle adjustments from now on, unless you have a wax paper slick track, you really don't need to use the punch. Throttle finger gets better with practice, leave it off is my opinion
