Sorry for my first post wrote while frustrated. I installed R77 full exhaust on 2014 hayabusa. I also installed power commander v, secondary fuel controller and auto tune. Bike is running like poop. No power up top at all. So disabled auto tune and took it to get dyno tuned. It has a hiccup at 6-6500k rpm he can't get out and it dynoed at 110hp. So called dyno jet and they say that their product would not interfere with the mode select. Seems to me that it's like it's stuck in mode c even when it's it's a mode. Somebody please explain what would cause this. It obviously has something to do with power commander not the exhaust. The tuner is planning on calling them tomorrow to try to figure it out. Anyone had this issue before or might know the answer so I can save time on getting bike fixed? Thank you
