“Bog” at certain RPM

Hey everyone. I recently installed the comp werkes decat and a coober ecu with a map for no cat. I know there is a bog when you sare in high gear at low rpm but its not that. While going 70mph in 6th for example, i will open the throttle completely and the bike will skip and lose power for a very quick second. Then is fine. This happens only sometimes but more often than not. This also happens in other gears as well. Is there a fueling problem or did I maybe install the Coober wrong? Or is it possible that its something I never noticed before and am just now seeing it. Your suggestions are much appreciated. Thank you.

It seems to be a feature of the bike.
The very same thing happened to me before I installed the Coober ECU.
Snap the throttle open, and it bogs down for a second.
I had to moderate my use of the throttle.

Check with Coober, it might be that the ignition needs to be readjusted.
On the PowerTRONIC I was able to correct this hickup myself by changing the ignition advance.

As long as you are happy with what you ride.

This was also a problem with the powertronic system. The fix was to set the injector noise level to 0.0
The system was to sensitive for the electrical noise of the KTM.
