I am getting a weird shutter/hesitation and back fire happening around 6k-7k rpm at certain throttle positions. I can either power through it with more throttle or just shift early. The bike is running the power up kit (arrow exhaust) with a power commander V with autotune (Doesn't appear to be working). I am not sure if it is the tune or something else. Curious if any one knows a solution or can help me narrow it down, a dialed map for an 08 SM450R would be an awesome start.
Thanks
