These statements tell me its not the radiator; it is an airflow problem: "Engine temps runs between 179⁰ and 183⁰ while driving" & "The only issue is when stopped in traffic I get a slow increase in engine temp". If the radiator was the problem, the temp would also increase at speed.

Looks like your choices are to either trim the shroud back to expose more of the fan, or reinstall and correctly setup those electric fans. If your e-fans were still running at speed, they weren't setup properly.
