Rev limit in reverse

[Bobatvracer]

I race hare scramble and occasionally I need to back up do to deep mud etc.. When I rev the engine up it cuts up and does like to put power to the wheels. What product can help with the situation ?? Thanks

I'm fairly positive that any aftermarket rev box removes the limiter. I have a Big Gun rev box and it removed it. DnB says he might ne able to check what wires to cut and splice to remove it without spending any money though.
