Mine runs dead on 180 highway driving or any type driving when the ambient temperature is less than 80F. When it's hot (upper 80s) in stop and go driving I'll get up to ~185-190. Before putting the low temp thermostat in I ran about 190 normally to 205 on hot days, all numbers according to the stock temp gauge. The biggest difference I've noticed is that the new thermostat reaches its operating temp and stays, whereas the original seemed to fluctuate a lot more. That could just be my car, but the 996 I had acted the same way and actually ran a bit hotter than the Boxster. I do recall that the MY97 986 I had ran cooler than my 996 as well.
