PowerCard offers you a tuning solution for your 1995-2005 Harley-Davidson Big Twin equipped motorcycle. The TFI controller can enhance drivability and throttle response on a stock motorcycle, and with the flexibility of the TFI’s tuning interface, you can easily change your fuel curve as you modify your engine. If you’ve already allowed your fuel injected 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.
