The key to your post is "computer says". Calculate the fuel economy yourself or learn how the gauge works.
TRD OR non-hybrid, I get 24+mpg in most driving since the day I picked it up at the dealer. I'm coming up on 12K and that's been really consistent. Over 70mph fuel economy drops pretty quick, lots of hills it drops quick, strong headwind it drops. Still, I've been on trips where I was in 4WD quite a bit, or driving a lot over 70mph and averaged 23mpg for the full trip. It's pretty hard for me to get in the 20mpg range unless I'm almost all stop and go. Long trip where I'm almost all 70-80+mph and I'll be down around 18-20mpg. I don't live in an area that is especially hilly, and biggest elevation change around here is about 1000 feet. I'm sure people out west will see quite different numbers. Those are just some different data points for different types of driving, but after 12K I know pretty much what to expect for any kind of driving and I've been incredibly impressed with the balance of fuel economy and performance, and having some flexibility to adjust that with the modes and how I drive.
Eco saves me maybe 1-2mpg depending on the type of driving. Sport drops fuel economy about that much but I don't drive in that mode a lot so I don't have as many miles and different types of driving for a fair comparison.
I've only recently seen the kind of poor numbers others talk about, and it coincided with temperatures dropping to around 0F for a few days. Since then I've been struggling to get 23mpg on any trip, and my numbers seem to be fluctuating much more. This is discounting a lot more idling which obviously is going to mess with the gauge reading. Guessing it's just the extreme cold, I'm not sure if the fuel formulation gets changed at all mid-season if the weather changes drastically, or there's only winter and summer fuel.
Driving style makes a big difference. How do you know you aren't getting into turbo, are you watching the boost gauge all the time? If you are in normal or sport mode it's very easy to get into boost, you don't have to be slamming the gas down. Any passing, almost any acceleration or uphill, when you are already above around 40mph will put you in boost unless you are incredibly light on the throttle. Eco helps with this. People who aren't seeing an improvement in Eco are pushing it too hard and basically forcing the truck to bypass a lot of what Eco tries to do. That being said, if I intentionally try to conserve gas, I can get pretty close to what Eco does in Normal mode, but it's much harder and I'm still usually 1-2mpg worse for any type of driving. Eco keeps the truck at a lower rpm in almost any situation and keeps you out of boost as much as possible, but again you can easily override that by your driving style. If you really mess with the modes you'll see this. It's pretty incremental. Normal keeps you at a slightly higher rpm, the turbo is much more ready and quicker to respond, and Sport is an even more noticeable step up there where the truck is always at a higher rpm and there's some small amount of boost almost all the time so you just tap the gas and it goes.
