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.

Please note: Modified cars may require injector upgrades. Please contact us for more information.

The ProFlex Commander product line is backed by a limited 12 month warranty. Learn more.
