PowerCard offers you a tuning solution for your 2006 Harley-Davidson Dyna. The TFI controller can enhance drivability and throttle response on a stock motorcycle, and with the flexibility of the TFI’s push-button tuning interface, you can easily change your fuel curve as you modify your Dyna. If you’ve already allowed your Harley to breathe better, with an intake, exhaust, or cams, now you need a TFI controller to give it enough fuel to unlock your modifications’ horsepower potential.

The TFI-1340ST uses GenIII technology, and was designed to work with the Dyna's advanced “closed loop” engine control system without triggering the dreaded “check engine light”. The TFI-1340ST allows you to take control of your fuel injection system, with TFI's proprietary load based tuning and easy to use interface. Supplied with factory-style plug-and-play connectors, this computer free tuning system gives you everything you need to upgrade your fuel injection system headache free. TFI gives you all of the control you want without any of the hassle you don't.
