Say it get's down to -15 or 0 at night, and 20 to 25 above in the day is it safe to run a tuner. And at what setting? S/C tow,tow/perf,perf. And for my new tuner PPE(not here yet) what setting would be safe?

:exactly: As long as you dont go out and pound on it without it warming up, you should be fine. I have had mine in -30° before, and I just let her warm up a bit, then she runs fine. I have run a performance product in all of my Duramax trucks in cold weather and have never had an issue.
