Was running at 260, now at 150?
About 5 months back I posted in here regarding cooling problems, put on a new air dam and it all sorted itself out.
The T/A's now ranges between 130 on cold days, to 160 on hot days. Is this too cool?... I'm fairly sure the gauge is correct, as when it was hitting 260 before coolant was spewing out of the overflow tank.
Car runs well enough, but a lot of people on here seemed to think the optimum was about 180/190 or so.

you just changed the airdam? Thats quite a drop. Sounds like your former airdam was beat to crap, or you have a faulty temp guage.
