Backfire when opening throttle

Can anyone help?
I’ve flashed the unrestricted map onto my 2017 R1 EU spec bike. I have a k&n air filter and a pipewerx decat exhaust. It all runs ok but when I begin to open the throttle back up after rolling off, so I’m still moving at this point, I get one very loud bang from the exhaust. Does anyone know what might be causing this?
Thanks in advance

In case anyone else has this issue, it seems to be only when I have the fuel cut enabled. It appears to be when opening the throttle back up that the initial charge of fuel ignites with a bang as the engine restarts.
With the fuel cut disabled this doesn’t happen, I just have the crackling on the overrun.
Have you got the AIS block off plates instaled? Mine souned like Gods own machine gun on the overrun untill I did that! 😂
