Under warranty until 125k shes at 88k. And im not necassarily looking for speed, just want a better passing gear lol. The answer to my question lies soley in the dyno graph comparison, i guess im just trying to gauge the magnitude of difference based on experience.

I have to disagree with this statement.
The torque output of 5.0 exceeds that of the Ecoboost only above 5300 RPM or so.

Yes, the Eco has low end torque (about 100+ lb-ft more at highway cruising speed) but it also has mid and upper band torque as well.

For highway driving, the Ecoboost will downshift less and pull hills at lower RPMs. A friend has a Ram with the 5.7 Hemi. He and I were going camping in my truck when he made the comment "does this thing ever downshift?"

Take a cruise into the mountains and the difference becomes dramatic.

I agree. Watch the RPM when you accelerate to pass.

I've had both engines and here's how I judge them. The 5.0 in my '11 Lariat was a little slow until you got up to 30-40 mph then it kicked in...this is probably because somewhere in the engines pedigree.. it thought it should have been in a Mustang and not a 150! Not a bad engine but a higher rev-er then a low end torque engine more suited for a pickups main job...towing or hauling. My '13 Platinum has the 3.5 Ecoboost and when I first drove it you could tell it was more suited for the work a pickup was made for and had way more pull from a dead stop. Hauls a load and pulls a trailer from the start with ease. Amazing little displacement (213 cubic inch) that thinks its a diesel! Both of my trucks were 4x4 Screws and the only drivetrain difference is the taller 3.31's in my '13. Fuel mileage on long trips is pretty close with the slight nod going to the Ecoboost which is about 1 mpg more...maybe a little less rpms due to gearing. I'm also in Louisiana so basically flat highway driving and no mountains or hills to contend with other then the Mississippi River bridges!

So which one is the '13 ??

PawPaw

Ecoboost Platinum is the '13...my mistake! See what you have to look forward to when you hit 68!!

If it were a Dodge, they have a flash counter. Fords do not at this moment, at least at the dealer level. Maybe a Ford Engineer could figure out if it was flashed, but chances of that happening are slim. They arent paying an engineer money to see if you tuned the vehicle.

Also, "logging" a pcm would be reading data coming through the OBD2 from the sensors. You can log a stock truck and not actually change the tune. I think you meant flashed which would be changing the factory tune file. Regardless, Ford cannot tell unless you tell them or leave the tune in the truck when you try to get warranty work done.

On top of that, unless the modification itself is related to the issue, they cannot deny you coverage. Example, you put a cat back exhaust on the truck, and your A/C goes out... They cant say well he put a catback on which changed performance and killed the A/C. Magnuson Moss Act.

Its funny you mention A/C work. Just dropped it off for an A/C compressor hahaha. Anyhow, so the reflashing/covering tracks can be done via aftermarket tuner? Or does it have to be done by a car tuner.

I just did 5600km of highway with my Eco over the past couple of weeks. I also was able to get some seat time (600km) in my uncles 5.0.

My observations are that the additional low-end torque is very noticeable in the Eco on the highway. I'm pretty sure at 2000 rpm the 5.0 has laround 225ft lbs going to the wheels, where the Eco has just under 300ftlbs going to the rear wheels (based on the dyno graph below). This is a massive difference! Add to that, mine is tuned and shifts way better than stock.
The 5.0 is a 2015 supercab xlt with 17" wheels and 3.73 gears. It did feel sluggish under partial throttle and you felt that you were really having to lay into the pedal to gain speed. Don't get me wrong though, when you floor it, it goes! Lot's of power on top and I'm sure if we lined up stock vs stock, it would be close. I would give him the edge if it was a 1/4mile or longer. I think I'm going to get him to tune it and then I can see what the improvement is (he doesn't like the shifting either).

I can see different types liking the different motors. For me personally, I love being able to gain speed and climb mountains with little revving and downshifting.

Just like others though, I suggest taking one for a good test drive and see how you feel about it. They are both impressive motors.

Thanks for the input! I really appreciate it!

The 5.0 has a touch over 225 ft/lbs at 2000 rpm.... I think you looked at the wrong graph.

And regardless if you tune a 5.0 interstate driving becomes much better. Once you get rid of the terrible throttle delay and delayed shifts you can drop down a gear or two and do all the accelerating you need to when you actually need it to unlike with the stock tune that likes to dangerously wait half a mile to make anything happen.

The "lack" of low end torque doesn't really phase the 5.0. 1st gear is so low that you're in peak power in no time. And if you want more power while cruising you just hit the go pedal and let it downshift. These transmissions and motors are pretty stout so don't be afraid to let the tranny shift down a gear or two (or three if you're really mashing the pedal) and let that coyote howl. Even the stock intake noise is addicting on the 5.0 so I don't know why you wouldn't want to give it a little gas.
