Full throttle slams the valves closed.

We need a valve controler.

I remote started the cold car right behind the exhausts. No rattle of any kind. We do hear things differently, and I'm not doubting what you said, but non-issue for me. As to reinstalling the module with power removed and valve open position, you can in fact do it. Simply start the car--the slotted shaft on the module will be full closed position. Get the car to open the valves--the shaft will rotate while you watch, then quickly disconnect the plug. You can then put it back on the housing and the shaft will keep the valves firmly in the open position. Would need to do it twice, of course, but if the 'rattle' bothers you, I would do this.
