I was going to put a tuner on my bike and get them to put it on the dyno as well (intake was done when I bought it, have put on slip ons and was thinking true duals). But my 06 doesn’t have 02 sensors, so is there tuners that don’t require them?

 

Yes, they exist. They're the best tuners in my opinion because the system always stays in open loop so you'll have complete control over the fuel map at any throttle position. Commonly they piggyback onto the wires going to the injectors and just increase the duration the injector is open based on your settings. Dobeck is one manufacturer, they work well and are reasonably priced.
