160* Thermostat...
The lower-degree rated thermostat will open sooner, making the flow higher, and keeping temps down.
This is also aided by the addition of a fan control switch (to manually turn on the fans when you want to) and/or the re-programming of the PCM to turn on the fans at lower temps.

It does its job when your getting plenty of fresh air and moving.. But once you get into traffic thats where you need a fan switch to drop your temps. Or have your fans programmed. Slight drop in MPG from running cooler though.

I have stock fan settings and my car runs at 160 on the highway with the 160 stat. Runs cooler all over. Fans rarely kick on.

Your car cant run at say 160* when your in stop and go traffic when your fans are programmed to come on at 215*. So with the thermo opening sooner you just have coolant flowing thru your motor sooner, thats still going to reach a certain temp before the fans kick on.

Just because you dont live in a city or somewhere there is alot of stop and go traffic doesnt mean the original poster does. I should of been more clear and broke down all the geographics of the US. No matter what, running a 160* stat without the fans being reprogrammed does not help if you live somewhere where it gets hot with a lot of stop and go traffic. Its been proven you dont even need to run a 160* stat in a LS1. Just by reprogramming or using a manual fan switch to have the fan come on sooner with even a stock stat makes a huge difference in the temp of the car.
I just wanted to add that the only reason I run a 160* stat is because I live in Vegas with a lot of stop and go traffic and in the Summer it gets 120*+ alot.
I dont know if your disagreeing or agreeing with me, but either way I know what you are saying. It just doesnt apply to everyone.
i gotta put my 160* stat in. its just sittin here lookin at me. I have my fans on a switch, but soon, i will reprogram with my hptuners. then i can take that old switch out, and put in an arming switch for future plans......
