Thats interesting, I guess the more HP the hotter it runs right?
I itstalled the 160 thermo without a tune and I now run (06 A6) 178 degrees highway (70 mph) and only 185-200 in traffic in the hot Florida sun, and thats without the a/c fan running

1. Any downside to the lower thermo - ie computer fuel settings, etc?
2. What is the coolant boiling point?
The only way that I found to cool down my C4 was with a better radiator.

I totally dissagree. My 08 runs about 196-198 in "normal" driving (cruising). My oil temp actually runs about 10-15 degrees cooler due to the new oil cooler.
Now, if ya'll are talking about when you are running a little harder, then I agree. The best way to compare is to go out on the highway and set the cruise to 70mph for 10 miles or so and see what it is. My coolant temp runs right at 196 or so in cruising - even in hot weather.

My 08 runs at 198 in normal driving. Are there any disadvantages to installing the 160 thermostat?

Pros and cons. If you go with a 160 t-stat then you should reprogram your cooling fans to come on at a lower temp. Otherwise, in stop and go traffic, it'll heat up just as it does with the 192 t-stat. Cooler temps mean slightly more horsepower. Personally, I am leaving mine stock. There are other reasons for the temps that GM has calculated other than just emissions.
