TQ is how far you take the wall with you
I did just fine in physics class

If you anything short of 100% throttle, you will not see your dyno results. 400ft lbs, unless, you are able to lock your gear while driving, you won't see this as you will down shift and jump up in rpm.
Turbos will spool within a couple hundred rpms from steady state.

The only physics I know is LED's do not emit light, they suck darkness...

I sure don't detect any.

In other words if it is producing it where is it going if not to the wheels.
when my 5.4 produces max tq it is gaining speed, when it is producing less I don't gain speed.

I'm new to this but I suspect that when you are just cruising around town at a steady speed the turbos aren't doing anything. When you put your foot down they will kick in. It's nice to have available and also nice to not use it all the time and waste fuel.
The small displacement of this engine helps to save on fuel use.

I put in solar a few years ago, assuming NOTHING breaks for 26 years it will have paid for itself.

Think of it this way. If an engine is making more torque than it needs it speeds up, if it isn't making enough torque, it slows down. This works from idle to redline.

Hope this helps clarify a little bit, I am no expert, but I have played with cars quite a bit, from little turbos (this being the smallest), to larger 98mm turbos, from single to twin to sequential. They all have their pluses and minuses. I have alway like the twin setups, and Ford has done a great job setting this up. If they went bigger with the turbos and left a bunch of power on the table, we would all be experiencing turbo lag more than we are now. This is how a perfectly setup trubo system should run for a daily driven truck. A sports car, some would expect more lag, but in return, you would have more upper end.

What everyone seems to forget is that the max torque and horsepower rating are at wide open throttle...you think you are going to get 20+ MPG's at WOT? It takes fuel to make power and torque. They get great mileage when empty or pulling VERY light loads. But when pulling heavy loads, as proven in several tests, they are very thirsty like ANY other motor. Power demand = fuel consumption. The EB when pulling a 9000lb load got 7.2 mpg's (Car and Driver test). If you are pulling trailers and heavy loads every day, why would you buy and EB? If not, then it might be the perfect motor for your application. But if you bought the F-150 and are going to use it for a truck and have a trailer behind it most of the time......
Never stated that I, or any EcoBoost, was going to get 20+mpg at WOT.
Most trucks do not pull heavy loads or trailors every day. Most are used as daily drivers, commuter vehicles, the new family car. So "yes", the VERY light loads (where most F150's are used, look at any Wal-Mart parking lot - there will be 20 full sized pickups with empty beds) make it a great choice.
Never stated that I, or any EcoBoost, was going to get 20+mpg pulling a heavy load. Most of us except the we will use more fuel to move more weight. It just nice to know that for 90% or more of the time, I'll get good mileage.
