Big Gun Rev Box is a must have! Adds up to 8-10% more horsepower once snapped in. Comes ready to install and go. Allows RPM to rev out much higher than stock while advancing the timing for a bit more torque on the bottom end. Get yours today don’t let the competition pass you by! Highly recommended product by the entire Big Gun staff.
