My recommendation = Self Learning Module (SLM) by Accel.
I've also used a SERT and Revtech DFO as well as HD downloads. SLM may set you back a few bucks but it will tune to anything you throw at it without the need to be a computer genius and without the need for costly dyno runs. Its about as plug-n-play as you can get.
Get it dyno tuned.
Its the only way to get your bike tuned to exactly what you have on your bike.
I took all the baby steps trying to save money with tuners. In the end getting a dyno gave me what I was looking for. A perfectly responsive bike with constant power through every gear.
I'm just sayin...
