We here at Roeder Racing prefer to use the TTS master tune system or the Screamin' Eagle Super tuner. These two systems are the most efficient and affordable, in our opinion, but you have to know how to adjust them.
We can also dial in a Dyno Jet Power Commander system. There is no substitute for running your motorcycle on a dyno and seeing what exactly is going on with your fuel injection system. The Dyno Jet Power Commander and Thunder Max systems work the best when dialed in on a dyno.
Here is an example of a tune on a 113. The red line is how we recieved it from an inexperienced tuner and the blue line is the end result from our tuner.
Each of Roeder Racing performance packages, gets a before and after dyno run so you are able to see what you paid for!
