Trying to carry some of the torch as others did for me when I was full of questions.
We have an introduction area here for you to introduce yourself and show off some pics of the ride. Maybe share some of the goals you're trying to achieve with the ecoboost.
Bunch of wizards around here to help with most any questions you have.
Best of luck with the ecoboost, and be sure to keep us posted on the new feel. I'm sure you'll be sporting a pretty good grin for the next few days, along with eyeing up the cars next to at intersections.

Welcome Dash!
Here's how I describe it to friends (and Rich step in if I'm wrong)...
Consider a scale of 1-10, 10 being totally balls out and potentially dangerous to longevity. Ford sends us these cars at a 6.5. It's good, safe, and best of all, it lasts a long time. What Livernois does is with the 4+ 93 they turn the dial up to 8. Very respectable, quick, and still very safe.
Now, 4X 93 (with 3 bar MAP sensor) turns it up to 9.5 BUT does so while still retaining the safety and longevity of the engine.
Consider though you're going to floor it more with the tune so longevity certainly isn't maximized. And just by turning up the boost, trans pressures, etc you are also causing more wear than if left stock. It is still safe but understand your squeezing more from that V6.
LME cares about their work a whole lot and will not give you (or anyone) a tune that will blow a motor.

Well 4X is just more "oomph". Shifts are about the same it's just more nut coming from the turbos so you have a really flat torque curve. Let's say 4+ adds 40hp over stock, 4X feels like an additional 15-20.
What makes you ask? You're allowed to have 4 tunes on the MyCal so might as well get both and try both! Plus free tunes for life so you can get new ones whenever you like.

In talking to Dan (head LME tuner) he advised me that "if your SHO is your one and only car, your daily driver, I would not recommend running the 4X all the time. It is a hot tune." I said it's my only car (I'm only 23) and explained how the difference in power justified the risk I was willing to take. He respectfully laughed and said he believes it is a safe tune but still recommends the 4+ for daily use and the 4X for track, drag, or when you know you will be driving fast for a day or two.
Plenty of people running 4X on their SHO/MKS every day with no problems. But said people are also keeping on top of maintenance, like Rich mentioned. So if you are sure your vehicle is otherwise sorted out, NO hiccups, move up to 4X for your DD. But if you have a doubt, stick with 4+. Getting to know your vehicle with Torque Pro on an Android device is a great way to do it (non-LME approved, but will give you a rough idea).

It's tough to pinpoint the specific changes, but essentially 4+ was already king of the hill when it came to tunes, and was what we used to call "use at your own risk" since the community has evolved and people are staying on top of things more than most car owners, we moved 4+ off of the "restricted use" list and developed 4+ to be king of the mountain, not just the hill 
Now, we still state both are use at your own risk, because in the wrong hands these cars can break when completely stock, but 4+ has been used for daily drivers for 60-70k miles without issues, so in the right hands 4+ and 4X could be used frequently. One thing we do note is 4X is 93 only, where 4+ we do have for 91 and 93.

You know better than me in all honestly. Sorry if I am further confusing things here.

As long as the tune is a 3BAR MAP specific tune for 91 or lower octane, than yes. The 3BAR tunes will be labeled "3B or 3BAR" typically to make it apparent the tune will not run on a factory 2BAR MAP.
