Dump Valve Problem?

Hi all, tried searching but couldn't find any answers on this.

recently installed a new "Le Mans" Group A Twin Piston Atmospheric Dump Valve on my my01 bug eye. sometimes the valve is loud and other times its quieter when venting at the same revs. also i notice when the valve does blow off loudly, when i select the next gear, before i depress the clutch, the volume of the valve goes from loud to quiet in mid dump. the dump seems retarded and i have noticed that the rev counter momentarily jumps up before coming down when i lift off.

Any ideas would be greatly Appreciated
