I've never seen, adjusted or otherwise dealt w/such a device, but then I've not hotrodded or even worked on 20-series truck emission devices.

GM came up w/a LOT of Rube Goldberg-ish devices to deal w/emissions, and this is yet another one that needs to be relegated to the trash bin- as long as your jurisdiction's emission testing doesn't require you to keep it.

I would consider it TOTALLY superfluous and I wouldn't hesitate for an instant to remove it and it's related encumbrances- or at the very least to render it inoperable (like what seems to have been done previously) and retain it for visual inspection compliance only.
