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?

You should really be able to run whatever you want, however you will need to let the truck get as warm as it can before you try to do some serious driving. I would think that in that temp you would not be going places to fast.

Let her warm up good and choose your poison....

: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.

I havent been able to punch it yet thanks to the roads and this white crap that continuously falls from the sky making a mess.

I run on Predator 85 h.p. and it rattles a bit more when its cold but I will never get on it untill Its fully warmed.

Just make sure and let it warm up. I ran the quad on my LB7 in -35C and it was fine(175,000kms). Just don't get on it too hard until it is warm. You will hear it. It sounds like it is biting the air until it warms up good. THe winter front is a must as it will never get warm enough without.
