I'd install the complete Dinan axle back if it improves the idle drone, but suspect it might make it worse. Anyone with this same setup please chime in with your experience regarding the drone.
Had the exact issue with my setup I referenced above, friend. Believe it or not, if you permanently open the exhaust valves, either with the fuse method or with a controller like I did, the drone goes away.
