The E-Force Stage 2 system offers you greater power gains than the Stage 1 Street Legal system. Unlike the Stage 3 Pro Tuner systems the Stage 2 includes everything needed to complete the installation. In addition to the base supercharger and components, the Stage 2 System features parts like a smaller drive pulley, competition air intake system, high flow fuel pump and a custom tune. All of this turns a conservative street legal system in to a race ready monster, achieving more horsepower and torque that todays racers crave!
