how to adjust for 160* tstat

[whackem04]

im putting one in and read about getting more spark advance by a cooler t-stat and want to know what to adjust for more power and mileage.
I have logs and tunes if someone wants to help.

I guess you have changed fans setting and {B4501} Idle Learn Minimum Temperature?

Yes and check to make sure B5910 doesn't throw off timing for light throttle application.

i did change fan settings. i never touched the idle learn and it is idleing correct. my truck seems to be running ok but i would like some opinions.
my 5910 is set to 0 until 203 -1.
