No custom chip. The PCM was reflashed to run with the 3L.
The water pump is fairly new but the radiator is original equipment.
What puzzles me is the stock temp gage sits smack dab in the middle of the NORMAL range when the temp is 217. Only during spirited driving does the gage creep up and even then it's still in the NORMAL range. For my own piece of mind, I replaced the stock gage temp sender. It seems rather odd that my engine is running hotter than it should but the cluster gage reads as normal.
