seems to be some mass confusion concerning 1/12 scale, with ESCs
Punch control = current limiting, nothing more... all ESCs have it as a tuning option even in blinky mode
some ESCs like Hobbywing V3.1 have two stage punch customization, for making a car more controllable at low end and full punch where you select it to be....again this is not boost. clones from Sky Toro TS120, Gforce 1S 120A, therefore have the same option and possibly the Cerix PRO 120 1S
Newer HW brand ESCs have punch control in a different way called softening value.
Softening function (HOBBYWING-initiated) for milder or wilder driving control and better driving efficiency you can add softening in lower throttle range like 0-30%, hence taking away punch, and then have zero softening at 30%+ throttle, which is full punch. hence two stage punch
zero softening = full punch
Boosters enable racers to use ESCs from their buggies, TC,s and cheaper just stock $48 low end esc's. they do not boost power to the motor, they are used raise the voltage for the receiver and servo
