Try rolling in the throttle a little slower instead of stomping on it. See if it feels any better. The torque management may be a factor.
The linear power of the 5.0 certainly makes the experience different, the power grows with the RPM. The Eco is fairly flat and with the stock tune feels just like that, good burst off the the start, but the acceleration level stays fairly flat.
A tune will make a huge difference, Tremors post up some of the fastest times 0-60 and 1/4 mile times with just a tune.
If you look at a tuner, get a device that will allow you to monitor a few parameters. You may see something that leads you to a solution or at least an improved experience. Monitoring boost levels and throttle position as well as Knock retard provide some really good info. Also if you get a custom tune for ma tuner like 5*, you can submit logs that the tuner can review. They may have some input.
Posting up current 0-60 times and comparing to others may help to see if your truck is way off base or just how it feels.
And run good gas.

Even if you floor it from a stop, the ECU will only tell the throttle blade to open a certain amount and it's nowhere near 100%. It does the same when you are getting close to a high RPM shift. It slowly closes the throttle so the shift isn't as harsh.
A factory Eco with no brake boost off the line and you just floor it generally will not start to break tires free until a few thousand RPM. That's when the ECU allows the throttle to open more and of course turbos get going more.
A tune of course will change all of that and make a night and day difference, however just to be sure, if you have the OBD2 scanner that is compatible with Bluetooth and happen to use an Android phone or tablet, get TorquePro from the app store and monitor boost levels, check for any stored but not displayed codes, A/F ratio's, and throttle percentage. You can at least start there to see if it is functioning correctly.

What should I expect for boost pressure with the stock tune?

Boost should be around 14.5 psi on a stock tune.

My 2013 4x4 crew cab ecoboost will break my 34"tires loose from a stop and spin them at times, stock.
Have you noticed more air whooshing sound then normal lately when getting on the gas by chance? I ask because my truck was feeling sluggish a few months back and I decided to do the VTA mod just for the hell of it and when I did I got a crazy loud air whooshing anytime I was on the gas. I got the sound when I was not vta Also but was much less noticeable.
I pulled my bov and inspected the diaphragm and sure enough it had a small tear in it. I picked up a new one at dealership and replaced it, I could not believe the difference in power afterwards!
May be worth checking.

How's she goin' eh?
I don't have experience driving an ecoboost but I am able to squeal those scorpions with my crew cab, I also have a 5.0L and 3.73's. I would hope a tremor configured truck with 4.10's would make those tires cry. I'm also surprised what I'm reading.

I never drove a 5.0, but I was disappointed with the 3.5eb’s initial throttle response when test driving them, but I bought one anyway. The couple 2.7eb’s I drove seemed to have better throttle response than the 3.5eb.
A tune did help for me, but from a start there’ still a delay. I’ve gotten used to it and don’t even think about it now after owning the truck for about 4 months. I bought the gauntlet of 5* tunes and eventually made it up to the 93perf tune, and I will say it’s a night and day difference from stock. I went from chirping tires sometimes from 1st-2nd, now it’ll sometimes chirp from 2nd-3rd. If I’m going 20mph and hammer it, it’ll roast both tires where it would have never done that stock. It’s actually a tad radical for me, I’m going to step back down to the 93 tow/performance tune which seems better for day-day driving. FWIW, I’ve got a screw with a 3.55 gears.

I want to start this thread with a note: this is not an Ecoboost vs 5.0 thread to determine which one anyone thinks is better than the other for whatever reason. We have enough of those threads already, so if that's the route you want to take it, please post in one of those threads. I think I'm having a legit issue and am looking for those with experience of owning both. Thanks in advance for not going there.
Now, on to the issue. I bought a 2014 Tremor, Eco with 4.10 e-lock rear. My previous truck was a 2013 RCSB 5.0 with 3.55 rear, and before that was a 2011 XLT 3.7 NA v6. Of the three trucks, the tremor is a turd. The 3.7 extended cab (don't know the rear gears, but I know it wasn't 4.10) had more snap and accelerated faster. Yesterday, just to make sure I wasn't crazy, I turned off traction control and advanced trac, and floored it from a stop. It wouldn't even chirp the tires. I even did it on a turn and still couldn't get it to break loose. That definitely isn't right.
Is there any way to test to see if both turbos are functioning properly? Is there something else that could be cause an issue? It doesn't stutter, I don't have any hesitation issues, it idles smooth. I replaced the plugs not long ago, and even the old plugs looked fine. It only has 31,000 miles on it. There are no codes that I know of (no indications on the dash). I do have a cheap OBDii scanner I can hook up, but with no lights, I didn't figure I needed to.
Has anyone owned both a 5.0 and an eco, with at least the same rear gears, and can offer shed some light on their experience with both?

I might have called you crazy not have seeing this thread (I have a 5.0 and haven't driven a tremor). I would think that the 3.5 w/ 4.10s would be a monster off the line. Good info to know.
