I checked the air pressure because it also pulls to the right which is another proplem we can't seem to resolve so I checked and they are at 35psi, is that where they should be?

Depends if it was hot or cold, but that looks ok, probably a little high...
If you are using an ethanol blend. That alone will reduce you mileage by 2-mpg. Now it's winter. The two are a bad combination for good mileage. I do get better gas mileage at 65. But I can't stay there long. I just can't. I tell you I can't.
You're hitting the nail right on the head. Ethanol blend will reduce mileage all by itself but just colder weather will do it also. Remember any engine will get less mileage per gallon when the engine is cold AND it is programmed to run MUCH richer in order to run smooth until the engine reaches operating temperatures. Some of you may have already reached your destination before the engine is running effectionately. Then you shut if down and the engine cools down again and now your going to do it all over again. So if your making a lot of short runs like to work or grocery shopping your going to get TERRIBLE mileage but it's not the trucks fault as ANY vehicle will be doing the same. Your just noticing more with a HUGE V-8 engine.
Cruise at <65 MPH, 16 MPG.
Basically no mods. If there really were mods (CAI, TB Spacer, Cat-Back, new chip, etc) that gave you 2MPG improvement, and cost a few hundred bucks extra, don't you think the Toyota engineers would put it in? Come on, that would be like 15% better gas mileage! They could advertise the sh!t out of that!
I'm sorry, but I'm a sceptic, and I think all of these testimonials are WISHFUL THINKING!
So there.
Why would Toyota engineers want to add them as a standard on the Tundra, when they can make more money in the after market? TRD accessories exist on the aftermarket and are not added as standard to the truck to keep the initial cost of the truck down. The TRD exhaust and TRD CAI do make a differnce, and of course adding a tonnneau cover is a no brainer as far as fuel economy goes.
i havent noticed a difference with my tonneau cover. And Toyota will definetly do its best to get every MPG out of the truck they can. The more efficent it is the better product they have to market. I disagree with them wanting to provide TRD acessories to increase MPG.
The same with HP i think that they will put as much power into the truck as they can while staying cost efficent.

The TRD accessories are a huge revenue source for the dealerships. They make more money this way then they would if they were already included in the truck itself. If you look through differnt threads on posters comparing thier trucks with and without these accessories, most of them will post differnces and many people even include track time slips to prove it.
This is a dumb argument. If Toyota could get proven increased mileage by selling Tundra's with these options you can bet your last dollar they would. They are under great pressure from the government to increase mileage on ALL their vehicles and if this would work on their trucks it would be STANDARD equipment.

Why would toyota come out with performance accessories that had no affect on the truck's performance??????? Thats not the TOyota that I know. Besides there are MANY other things they could do to make a tundra more fuel efficient if they wanted to make the truck more expensive and sacrifice the aftermarket. Here is a link to the department of energy's website that contains possible modifications to improve fuel efficiency. Toyota has adopted some of these VVTI, but not all billybob.
I have personally added on TRD exhaust , added a drop in air filter, and added a tonneau cover. After adding those accessories on my 4x4 Tundra I have noticed a 1-1.5 MPG difference. : )
I have one word for you: Naive
Toyota sells the aftermarket stuff because people want it. Why do people want it? Because they want the FEELING they're doing something COOL and UNIQUE. What you're doing (sorry) is following the crowd.
There was a time when customizing your vehicle and engine was performance enhancing, but that time is gone, at least where economy is concerned.
If Toyota didn't sell custom add-ons, someone else would.
I'm not talking about a supercharger now: that would definitely make a difference in power anyway (maybe MPG too, I'm not sure). But it's very expensive, around $5G so they're not just going to throw that on.
I added a tonneau cover: difference in MPG: zilch.
.
People adding to their trucks and charting performance changes need to be very rigorous in their science, make one change at a time, calculate fuel flow with accurate fuel flow meters, account for differences in fuel age, air temperature, barometric pressure, driving style, etc., etc., and they'll find miniscule improvements if at all.
If you want good mileage, don't buy a truck.
If you want to get there regardless of weather or road conditions, you have the right vehicle.
If you want better mileage stay out of the accelerator, drive <65MPH, keep tire pressure at max.
that's my rant for the day
