Two brothers cyclone exhaust and a k&n air filter. Also removed air restrictions in the air intakes. Paul sent me instructions to take the air restrictions out through the air box, so much easier than taking the fairings off to get to the air tubes. Just a few more screws to loosen the air box cover while your changing the ecu. They come right out through the top. Oh and I’ve ridden 143 miles with the tune with no gas light coming on. I don’t think tune changed fuel mileage much.Did you do other mods, or just the tune?
Can't wait until I get the ECU back from KCS and try it out!
