Our new piggy-back style Fuel Programmer is the best overall choice for adding the proper amount of fuel to your 390.    It's better than aftermarket ecu's, for most people.   Because we have designed it specifically for the 390, it's the only option out there, that actually richens the fuel up, when you get on the gas.

       You can set this ( on your own, in seconds ) to run from 14:1 to 10:1 afr, past 8000 rpm. So it will handle ant any mods you throw at it.  It's the only thing on the matket for te 390, that does this.

      Because of this, it pulls harder than any ecu, under heavy throttle, when accelerating, or at rpm's higher than 6500.

      Very simple to use, and by far the best money spent, for performance, after adding our end cap.

       Also increases the fuel during the accelerator pump function, so when you crack the gas, the bike gets up and goes better.
