Thanks for the feeback. I would like my engine to poerate around 180 - 185. Can I squek by with a 170? Allen, does your truc run cooler on the highway? I understand you can control temp via. PCM by controling fan switching. However, wahat happend at highway speed when the air flow through the radiator is maximizing cooling? Won't the stat let the engine cool to its spec?

P.S. Since the new board has been up I no longet get e-mail notification on threads. Is there a setting here that I can change. I do not see one on these pages.
