Sensors before and sensors after demandy?

[Wildcard]

Granted this peticular engine might have water flow issue with rear cylinders being egr cooler removed and possibly not plummed in.

Is it possible that the radiators are engineered to handle the egr load, and if now missing the cooling system possibly be oversized? I notice with mine since the weight loss I now operate at t stat temps unless under heavy load, where as before I would constantly cycle between fan on at 212 and off at 190.
