Cold weather - how is your ecoboost running?

Mine is taking a bit longer than usual to start, and seems to be idling rough sometimes
(it usually doesn't get better when it warms up, however sometimes even when cold it doesn't idle rough so it is random)

Anyone else notice any differences in cold weather?

i suspect i might have a fouled plug, thoughts?

My start time is not changed due to weather at this time, and my idle is pretty normal, though I stay in high idle a bit longer due it temperature. Car is still silky smooth 99% of the time though.
Mine takes a bit longer to warm up, trans temp stays pretty cool as does cylinder head temp. Coolant warms up a bit slower than usual. At highway speeds, due to the temps, my RPMs are a bit higher than in the past, but not a huge deal. there is also some slight shudder at certain times before a shift where the torque converter locks/unlocks a bit extra in order to heat things up. Here is the feedback I got when asking about some things I saw. The fuel pressure is not a concern, as I now know, and Brad (AJPTurbo) added a bit more fuel globally to my tune which seems to have me fully sorted out.

There is SOME improvement with custom tunes, especially with trans behavior.  But yeah best to drive gently until the trans temp hits triple digits at a minimum.
 
We were consistently about -35 to -40 degrees Celcius for about ten days and my SHO ran just fine. 
She was garaged and had the block heater plugged in overnight but zero problems so far this winter.
 
I saw a huge improvement since changing my evap purge valve solenoid which completely fixed my rough idle and would also throw in a bottle or two of Heet preferably the yellow bottle before throwing money at random parts.
Do you have torque pro? you can certainly monitor your 02 sensors and check to see they need to be changed especially if original. Z
 
After reading a lot of posts on this subject I didn't know what to expect. But I can say mine runs as good as ever even with today's single digit temps and I didn't dial back on any tunes.

Ran mine at -25 here in MN and it was flawless (after letting it warm up of course). Trans takes forever to warm up though....

2010 SHO runs great in the cold single digits.. no issues... A bit more road vibration from the tires being harder from the cold. I did notice on colder starts that there is more fuel smell coming from the tail pipes.. but I have HFC DPs...

I experienced very minor (but noticeable) rough idle for the first time yesterday morning on my way to work while sitting in traffic.

Temperatures this morning were within 2 degrees of where they were yesterday and no rough idle. The only change? Last night I drained just a hair over 13 oz of liquid (903 SE WI winter miles worth) from my OCC. I tried draining it around 700 miles, but my drain was frozen due to cold temps.

Could be pure coincidence.
