It depends on the turbo's design. In a dual setup you can have one spool up early in the RPM band and the other later. Boost increases torque and helps the truck pull the weight. A struggling engine will drink far more fuel. Same principle goes with swapping diff gearing to a higher ratio. Fuel economy will be hit unloaded but improves with a load.
This is true for turbos in sequence but I believe the 3.5 ecoboost has a turbo for each bank of 3 cylinders. One for the left bank and one for the right bank. This should allow the turbos to be smaller thus more responsive.

Seemed to me the OP was trying to deceive us. Not fully disclosing all the necessary details. If so, then I'm correct to expose it, and only a Ford guy, in this case, could think me rude for it. Not to seem all holier-than-thou, but check Job 11:3
Whisperide, Thanks, and your comments are right enough, but I can defend myself. No offense, and I hope to meet you at the Cache Valley Cruise-In, will you be there?
How about you, mister offended local?
You guys seem to have no trouble mentally divorcing the truck from the turbodiesel engine, but you seem un-able to do the same for the Egoboost's turbo. Come on, get real. I don't have the forged pistons or direct injection of your Egoboost, but I can order a MasterPower turbo, a set of injectors, and get my 4.3 to the same 365-HP level for far far less money than the cost difference in pickups. Even if I had to tear-down and do forged pistons, I'd still be money ahead. You don't have to have the F150 just to get the results. You can do it with Ram or GM.

Why the hate for the Ecoboost? Maybe you just don't like new technology?
The option of building the snot out of an older engine has always been there, and it's a good one for guys who like to build and tinker with engines. Other guys would just rather turn the key and drive something with a warranty.
FWIW, even the new non-turboed V6 engines have much more power than the GM 4.3. The V6 GM puts in the Camaro and the new Chrysler Pentastar are good examples, with the neighborhood of 300 horsepower stock out of the box.

The basic technologies used in the Ecoboost have been around for 70+ years. Only recently however has Direct Injection become feaseable for mainstream use in the auto industry. They have also been able to solve the inhearent issues with boosted vehicles, mainly excessive heat.
If you enjoy 'tearing down engines' and such, by all means knock yourself out. I still do the majority of my own maintaince, but the idea of doing a set of rod bearings or a clutch job on a 4x4 makes me want to go new vehicle shopping pronto. I do my own work because I'm cheap, and I trust myself more than the average shop around here, certainly not because I enjoy crawling around on my back on my garage floor with road grit falling into my eyes. I've got MUCH better things to do.

I am keeping an eye on the EB F150 as a next TV when my diesel gets more miles on it. Seems time is the only wear factor not yet accounted for. I am sure they will get better and a 5.0 EB would seal the deal to many people. I still remember how painful the Rocky Mtns were on my previous Hemi and don't want to re visit those conditions.

That's where the Eco is nice. The turbo'd engines, elevation effects are effectively neutralized.
It's so unfortunate, everyone enjoys talking about the ecoboost(good or bad) but the biggest issue seems to be long term testing, and real life situations. Problem here being any time someone trys to talk about their personal experiences they get raked over the coals by someone, either claiming that the ecoboost isn't better, or that it is going to be a pile of junk.
I recently bought an ecoboost, and am hoping the hype is real, and that the haters are just hating for no reason, other than that's just what they do. To the OP good luck with the truck, we're hoping that ours pans out for us too,
