I've owned both the 3.5 eco and two 5.0 F150s. I actually just traded my eco on a 15 Scab, 4x4, 5.0, 3.55 e-locker with the sport package I love this new truck. I don't drag race or tow a ton, so I didn't need the extra torque. I missed the rumble of a v8, and I could never get used to the sound of the eco engine. Both engines worked great for me, buy like am earlier post said, it just felt wrong without a V8 under the hood.

 

Anytime you add more weight to wheels you're going to take a performance hit. I've got the 5.0 SCREW platty with 3.31. I think it rocks even in lower gears. I don't experience the lag etc your talking about. The tranny know my habits and downshifts nicely. I'm not a light foot either. Good luck to you. Have you considered going back to stock?

 

Yeah a regear would be a waste of time for you. I don't dislike the 5.0 entirely just its low end power I guess. I am hoping the new EB Ford is offering in the new raptor is available in the F150. If not Ill be waiting even longer for a used 17 raptor to come out as I don't wanna fork over the money for a new one.

As for tunes I like the idea I just don't know if I'm willing to take the risk on one. It may not blow up the engine but I just am afraid of engine knocking

 

It's hard to describe unless you drove mine. Don't get me wrong the truck has power but it's more just the power it produces when accelerating its like the truck starts to go bogs down a bit, then it's ok, then shift, then rpms decrease slightly and then the process repeats. It's much better when starting in sport mode the RPMs go right to 2k rpm and pull better off the line but I just don't like driving around in sport mode all the time in 5th gear. To be honest Ford should have made sport mode standard with all 5.0s until 5th gear.

I don't think I could ever go back to stock tires and wheels partially as I sold them but even if I didn't I like the wheels so much more. I will get slightly smaller lighter tires in a 285/65/18 vs my 285/70/18 I currently am running whenever these wear out.

When I test drove 2 EB I was shocked at the difference though. The first I test drove I spun the tires at 30+ mph on a wet road and the other EB I test drove seemed slower than my current truck. Might have been a 3.31 but they sure felt like 2 different trucks even though they both were Ecos

 

contact vmp and they will hook you up. You will be laughing at every ecoboost on the road. You will not regret it.

 

If I had the extra cash I'd love to add a turbo to the 5.0 and it would surely fly you're right. Not a big fan of superchargers though as I like the turbo whistle better than the supercharger whine. Wonder why you only see SC kits for the 5.0 and never turbos...

 

I would do two things differently if I could go back and do it again:

1.) I'd get the 2.7 with a 3.55 or 3.73 e-locker instead of my 5.0. For my purposes, the little 6 would still get the job done and save a good bit of fuel.

2.) If I got the 5.0 again, I'd get the 3.55 e-locker. Not that the truck's overly slow with the 3.31, and not that I really need the e-locker with 4x4, but would be nice to have.

 

Love my 5.0 even with 3.31, only regret I had was the small tank but that's fixed now. The power is there when you need it and I can cruise the interstate at 82 mph turning 2k rpm and still get 17 mpg with no air dam. And I am confident in the reliability of this engine also

 

Smaller market for turbo kits on trucks. Plenty of turbo kits out there for the mustangs, but the piping and intercooling would be altogether different.

 

No regrets here. I think 3.55s and the 5.0 match up perfectly. If I was going to run 35s I would have gotten 3.73s, but that's about the only change I'd consider.

There are other, non-powertrain regrets I have at times.
