A lower C rating wont slow down your truck (or the amount of current the lipo can deliver), moreover it will cause the lipo to heat up and go puff since it cant provide the current you are asking of it; like making a fat guy run, he gets hot and sweaty alot quicker than a healthy person would.

Punch control doesnt reduce total current draw either, merely the initial current when you mash the throttle, so it is of small benefit to run more punch control; no substitute to good lipos..
