High RPM miss when cool

Strange When it's cool out (mornings, 60F* or so) my bike has a miss above 7500 rpm. Just flat out refuses to rev. Runs fine in the warm afternoons. Pulls right up to the limiter. Any ideas? Plugs are new so its not that.

05 SD, single exhaust, factory air box, Akro Smoothed Map.

Thanks

Figured it out. The front coil popped off. Not completely, but it was not fully seated. Strange, because the plug is tight.
