@arains44 ive been having similar issues chasing higher than expected temps after swapping out to electric fans and inline thermostat mod. Turns out the Delphi temp sender I installed a while back is the wrong resistance and sends the wrong temps to the ECM. The OBD reading at 180F was reading 170F on an external gauge and 212F OBD: 194F external.
I had no reason to suspect the temp sender before I did the mods to lower coolant temps.
