I have a few mods including a procharger and can tell you that I have seen absolutely zero difference in anything at all using a 160 stat vs. stock. I will get flamed a bit for this, but that is my personal experience. No HP, No lower temps, No nothing. A waist of 4$. Maybe in cunjunction with a better radiator.

Have you logged any of your runs to see where your IAT and coolant temps were and if any timing was pulled?

A 160 stat will not make any more power, but it will keep your engine from loosing power from heat soak. I don't think it's the heat affecting the engine, I think it's the darn computer pulling timing on warm IAT's or Coolant temps.
Example: My inlet only A6 car on a warm June evening: First pull 334, second pull 316 rwhp. I lost 18 rwhp on back to back pulls. You could see where the computer pulled timing at 3200 rpm.
Next week with headers and a 160 stat: First pull 359 rwhp, second pull 360 rwhp. Car was much more consistent.

07, C6, Z51, 6sp, Kooks lt's, Corsa Sports outback, Halltech cai, 160* stat with tune for early fan engagement. 100* outside temp 182* Interstate driving, 205* in town driving and freeze your *** off at 30* outside temp or less in winter driving. The car did however stay at 182* at the Bonneville 100 mile open roadrace averaging 120 mph in the Nevada desert in June.

You really need a Fan Module and an Elec Water pump to see much more increase. Prior to my 160 Stat I was running about 198-200 deg. After the 160 stat I run @ 180-185. The heat kills the motor.

I have a 160 deg in my car...it runs at about6 170 at best.no more power that I could see from tuning but I like the fact it is not running over 200 like before. Also I would rather have my car runnng cooler...

I have had a 160 or 180 termo in my last 3 LSx cars. Operating temps were about the same --- right around 180 degrees or slightly less at cruise, 190 or so in traffic. I've seen what happens at the track or on the dyno when the temps get over 200 --- loss of power, ignition retard, etc.
I have never noticed any difference whatsoever in how the heater or defroster operated, even in the dead of winter.

True, but giving your heating/cooling system an extra minute or two to get up to speed (something I'd consider normal even with a stock t-stat) will. 
I can't speak for everyone of course but an extra minute or two on those few extrememly cold mornings throughout the year that most people would even drive their Corvettes on isn't too much of a sacrifice considering the upside/gains of doing a 160 degree t-stat.

Yes, switching the stock one in for the winter time is an option as well, especially for those who daily drive their cars in the extremely cold/northern climates.

I live in a hot climate and my car with a 160 stat runs at 167-169 on the highway at night and 170-174 during the day, I think it's a bit low and would like to be running around 180, I even got a low temperature warning once (actual dic warning "hot engine a/c off") because the coolant temp was too low while cruising on the highway. This happened on a cool night when I just drove the car straight onto the highway.
Having read other posts, I guess not all 160 stats are the same, some run cooler than others. Also, from my experience the only apparent drawback (other than the dic warning) was that fuel economy suffered a bit, haven't measured exactly but it was enough for me to notice.
Is my stat too opening too early? Is too cold bad?
