Spit and Sputter Ecoboost..
My 2013 when cold at start it revs up slightly and then idles down and sits around 1000rpms until it warms up and seems the thermostat opens up and then drops down to 500rpms and purrs nicely. But during the cold idle it seems to sputter alittle but seems to go away as it warms. I notice the 2 pools of water that collect underneath from the exhaust, one puddle comes from a tube right below drivers seat and other comes from the cat exhaust weep hole, would u say that the engine is pushing the collected water out of the exhaust and once out it idles smooth. Does anyone else have this with there Ecoboost?

Water collection is condensation from hot pipes and cool air. Basic chemistry.
The sputtering is just a quirk. I've never had any other vehicle do it but then again, I've never left my gas engines at a high idle for any length of time.

the spitting and sputter only happen at first start up as cold engine starts to warm. It seems as soon as the RPM's drop down to 500 rpms then it stops for the most part and off i go. Being winter i let it warm up until it drops in rpms, almost like the thermostat opens up and she is ready to drive. I also notice that until the trans temp gets to 105degrees she will slide nicely into 5th or 6th, i am usually doing about 50mph. I wish my dash gauge would show the gears like previous models do so you can see what gear your in.

Bump the select shift button up or down once. It'll display them then.
And mine does the same thing on a cold start. Doesn't bother me though. I assume its the nature of the engine. Engines don't like being cold and neither do I.
Your trans is shifting into gears and not locking the converter. That's why it feels so smooth. This is normal and helps to build heat in the transmission.

Let me add something else TO. You said you were seeing water dripping from a hose under the passenger side floor? Thats likely the condensate drain for the A/C. Were you running the defrost? If so it's condensing the water vapor out of the air which would explain that moisture.
Otherwise water out of the tailpipe is a byproduct of ALL internal combustion engines.

oddball, no defroster. I dont have anything on while it warms up. There is actually 3 puddles under my truck. 1 is at a connection pipe right below drivers side seat, the other 2 are weep holes that come out of the muffler, the only problem this is gonna create over time is rusting of these areas. There is already rusting on the drive axle and rear gear box. That is sad for a 2 month old truck. I barely had rust on my 2002 Super Duty. They must be using cheaper metals for it to surface rust so quickly.

Anything steel will rust. All vehicles have this. It just surface rust. Your only two options are paint them or buy aluminum replacement parts.
Quit worrying about your truck and just drive it.
