I have a 2009 R6. M4 midpipe with GP slip-on and PCV, I also did the airbox mod where you remove the snorkel to increase airflow. I'm not good at explaining things mechanically. But it acts weird sometimes but usually a restart solves the problem. If anyone can watch this video and tell me why it does this, it would be greatly appreciated. It only happens with light throttle. Wants to cut out. Seems to go through rpms fine WOT. Only other issue is an inconsistent idle, where it bounces around. Anyone else ever have the same issue occur?
