160* or 180* ?

[Mephisto]

ive noticed a lot of people using the 180* thermostat...

is there really any difference between the two? (besides 20*) my truck felt like it ran better with the 180*. do some trucks just run better if theyre hotter??? ive also heard you get better mileage with the 180???

Lucifer,

I've put in 160's on my GN & TTA and I think I lost mileage. Plus I think some of the computer circuits don't turn on w a 160 temp. I'm going w a 180 on my Ty rebuild.
