In a round about way he already has told AKA about his problem. Sully has answered his question with the reply above. Turning the LPR back to where it should be and lowering the Sidewinder to where it should be will quiet it down. Having the LPR too low will cause the pressure out of the Sidewinder to be turned up to attain wanted velocities. This will cause the "loudness" level of the gun to increase. There is a comraderie between the LPR and HPR for proper flow, efficiency and volume.
