If you look at those torque curves, the EcoBoost doesn't have jack for torque at 1000-1500 RPMs, because the turbos haven't spooled up.
At that RPM, it's just a 3.5 L V6. Yeah, it sips gas at that level, but you don't get torque and power until the turbo's kick in air into the engine.
At that point, you have to inject gas, or you'll throw a rod out due to lean condition. When the turbos kick in, you get power and torque, but that kills your gas mileage.
I don't think it's all its advertised to be, personally. I'm sure people are happy with their 3.5 L put-put squirrel molester, but wait until you hit 100k-120k miles and you have to shell out $2000 bucks for new turbos.
If you look at the dyno, the Ecoboost does make A LOT more power at 1,000-1,500 rpm at a steady state or while in boost. The only time it is not in boost is from a dead stop, and even then it spools up very quickly. The fact that it has little power until the turbo's kick in is no different that the MDS V8's having no power in 4 cylinder mode until the other cylinders kick in.
The 200+ Ecoboost trucks with over 100k or even 150k miles on them with less than a handful of turbo replacement would prove your "but wait until you hit 100k-120k miles and you have to shell out $2000 bucks for new turbos" statement incorrect.
