Choose Commander Pro (option below)

Choose the ProFlex Commander Pro for your vehicle if you have aftermarket forced induction or aftermarket 600cc/60lb/hr or larger injectors.  If you plan to make these upgrades later order the PRO.  It will work fine with your existing set-up and will automatically adapt when you install your upgrades.

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