Choose Commander Pro

Choose ProFlex Commander Pro for your vehicle if you have aftermarket forced induction or aftermarket 600cc/60lb/hr or larger injectors

ProFlex Commander PRO was specifically designed for improved injector function in forced induction and large injector environments.

Please note: this system requires tuning after installation to turn on factory ECU flex fuel capability. Your vehicle will require a professional tune as we have discontinued the Flash handheld tuner.
