EcoBoost and maximum power

Denver Ecoboost
One thing that I have noticed about my EcoScab is that the truck learns my driving habits like nobody's business. Typically I drive somewhat conservative and when I get on her, she just falls flat on her face. But then the next time I get on the throttle then the truck takes off like a rocket. I have about 2k miles on the EcoScab and the MPG just keeps getting better, loving it.

I've been watching the throttle position since I bought the truck. I noticed when I got the truck that it doesn't go 100% most of the time. I hoped that would go away, but I'm at 4500 miles now and it still acts just like when new. If they programmed it for reduced power, reducing throttle angle would have been the easiest way, but I saw no evidence of that.
I think the power and mpg improvements people see are due to mechanical break-in, as others have said.

As for hellacious burnouts, yea, if you want to do them you need to re-learn how to power-break (think back to when you where sixteen).

Turn traction control off and let the tires burn if that's whatcha want.

The lag is not from the turbo. Might be programing to prevent powertrain damage. My buddies 2010 5.4 f 150 is the same way. Same with my last 2 ford diesels, chevy diesel, and chevy avalanche.

I think the "lag" u speak of is attributed to the time spent transferring power to the rear wheels which isn't instantaneous with mashing the accelerator pedal. The turbos in the ecoboost are at peak power so low in the power band that turbo lag is virtually non existent.

When I talked to a Ford engineer at a customer evaluation event here in Houston and I was told that a small amount of initial turbo lag was programmed in.
In testing,the engineers had no problem making the engine lag free, but some driveability issues cropped up - the most worrisome was the idea of the engine hitting hard leaving a traffic light in winter snow or icy conditions; the traction control couldn't catch it before some tire spin got into play!
Also, in low traction conditions, slowing down to make a turn and then rolling on the power sometimes lead to the rear swinging out - not cool! The power just came on too quickly. The same thing could happen if you were rocking the truck trying to get out of a hole - crack throttle, too much power. The lag everyone feels is Ford giving you a totally controllable engine for the first tip in of the throttle.
Can you imagine being in a line of heavy traffic and everytime you cracked the throttle to move up a little bit the engine surged? That, my friends would suck!
The engineers I talked to were more interested in the throttle response after getting underway; in cruising conditions. Now the EB has no problem there - anything short of initial throttle opening in my FX4 is very direct - cruising 80 mph and opening up the accelerator gives an instant rush of power! Very nice.
I have found that I get the fastest 0-60 time from a dead stop by rolling the throttle open slowly at first; resist stomping on the accelerator - roll it open slowly and once the turbos are online, let her have it.
Now my Mazdaspeed 3 had instantaneous throttle response from idle on up but the difference there was it had a 6 speed manual transmission; the clutch, you see was the moderating factor. Simply feathering the clutch kept the overactivity gremlins under control.
And yes the truck learns your driving style and adapts - drive it like a grandpa and it acts like one for you. Drive it like you stole it and it has a much tighter game. I make sure to nail mine at least once a day to keep him on his toes, usually on an entrance ramp getting on the freeway. He loves it and frankly, so do I......
