My gauge never gets to the middle mark, Ultragauge shows a temp of 186 to 190.

But I had the "-10C" mod done to my car for $50 by Buckhead Imports and I recommend it to everyone. My fan's operating parameters are lowered 10C/18F by the mod, that is, the fan runs at much lower temperatures. I have no idea why they put a 190F thermostat in there and THEN didn't program the fan to maintain 190F. But now, mind does just that.
