I'm very happy with the tune from super bike unlimited. I have to resend my ecu bc my bike was stock when it was flash now that I have mods some things need to be change. They are awesome people. I was just emailing them and they respond fast. What happen was I was trying to get a hold of them in the beginning of the week but they were out of town witch I didn't know. But I am very happy and please with the ecu flash. My ecu has to go back for the exup code flash that's all.
