Yup...I dont think any is available yet for the 390...If the 390 is the same as the 2013 690 then there is nothing available due to no one having cracked the ECU yet. On the older models you can use either Powercommander or TuneECU. Im looking around at the moment as I really want to adjust the power curve from the back end to more mid/lower end of the range. Gearing will help a little but this engine is far to polite down low.
Welcome to the forum Pyscho.....now tell me more!Am using the race dynamics powertronic which is yet to be launched for the 390, it is a piggyback system that allows for ignition, fuelling and over rev too. Have seen gains of 2.5bhp on the wheel at peak but the rest of the rev range with the ignition mapping and fuelling really increases torque and rideablity and response.
