All Big Gun Rev Boxes are designed to enhance the rev limiter from 1000 rpm on most
models to 3000 rpm on others. By allowing the rpm of the machine to go over its normal
low setting allowing the engines to build the actual horsepower that they were designed for.
By moving the rev limit up we have been able to pick up 1-3 hp depending on the model.
