What tunes to run when its -30C

[Redram99]

It has been -30C here now and running the 250 I've noticed a few things, Boost climbs extremely quick and injector rattle(or some weird noise) when the engine isn't fully up to temp.

I have tuned down to the 125 and it seems to be better.

Are we supposed to do anything special in cold weather with these trucks?

I have a winterfront on already.

Thanks

Let them warm up a minute or two before taking off if possible

I know in diesel boats, during cold weather and warm up...the pistons actually shrink a little. So there is a very small shake as the pistons go through cycles, that's why a lot of diesels have block heaters to prevent this. HIGHLY recommend you let it warm up to at least 100 degrees if you can. I don't go over 2k rpms until almost at ideal running temp.
