    Well looks like the problem may be solved. Some of the wiring to the fans was corroded. Cut them down some, put on new connectors, and on the way home, temps stayed at 185 (with heater on high just in case). In town they went up to 190. Stopped and grabbed lunch and turned the air on and it went up to 200 and stayed there. So I guess it was corroded wiring and resulting low fan speed. Going to upgrade to 05 fans though and help it out more. These fans are great - just not for the turbo and underhood temps.
