Lol, average 14mpg hauling 15k? I think the computer is misleading you...

Well I admit the fuel efficiency is better when I set the computer to kilometers; I think it adjust the engine timing or something but it "feels" stronger.

Some cars use a device that can advance the valve timing. This does not keep the valves open longer; instead, it opens them later and closes them later. This is done by rotating the camshaft ahead a few degrees. If the intake valves normally open at 10 degrees before top dead center (TDC) and close at 190 degrees after TDC, the total duration is 200 degrees. The opening and closing times can be shifted using a mechanism that rotates the cam ahead a little as it spins. So the valve might open at 10 degrees after TDC and close at 210 degrees after TDC. Closing the valve 20 degrees later is good, but it would be better to be able to increase the duration that the intake valve is open

Several engine manufacturers are experimenting with systems that would allow infinite variability in valve timing. For example, imagine that each valve had a solenoid on it that could open and close the valve using computer control rather than relying on a camshaft. With this type of system, you would get maximum engine performance at every RPM. Something to look forward to in the future...

The Tundra uses a Double Overhead Cams (DOHC), a 32-valve head design and Dual Independent Variable Valve Timing.

Overhead camshaft (OHC) valvetrain configurations place the camshaft within the cylinder heads, above the combustion chambers, and drive the valves or lifters directly instead of using pushrods. When compared directly with pushrod (or OHV) systems with the same number of valves, the reciprocating components of the OHC system are fewer and in total will have less mass. Though the structures that support the system may become more complex, most engine manufacturers easily accept the added complexity in trade for better engine performance and greater design flexibility. The OHC system can be driven using the same methods as an OHV system, these methods may include using a timing belt, chain, or in less common cases, gears.
Many OHC engines today employ Variable Valve Timing and multiple valves to improve efficiency and power. OHC also inherently allows for greater engine speeds over comparable cam-in-block designs.

Ok, I forgot to add that I have a few aftermarket parts. I run a K&N air filter, split fire spark plugs, optima battery, and Royal Purple engine oil. These components combined together add atleast 70hp.

The other day I outran my cousins buddies Mustang in a drag race, and that thing is fast.

Well that explains it.................

Lol I forgot to add the Flow-Master pipes as well they add like 45hp. Before anyone was serious and gonna lie about what there truck can pull and there mpg I figured I would get that out of the way. I mean what's a truck comparison thread without some absurd mpg claim.

I do own a 2010 4X4 Tundra 5.7 and I love it but it have never done any of the things I mentioned above. It will maybe get 22mpg going downhill with a tailwind.

As far as comparing the Tundra to a F-250 King Ranch I say get the Ford Raptor; obviously $$ is not a real big factor and you don't need the F-250.

Any pros/con of the non-Diesel F250?

My 2007 Tundra never got better then 14, maybe 15 on a good day.

My Tundra was an awesome truck, was the first 1/2 ton that could pull over 12k, now its the norm with all 1/2 tons. When I got ride of it with 130K miles I didn't have a single problem with it. But I needed a true 4 door cab and long bed, as well I needed more pulling capacity. You can not get a full size 4 door with a long bed in the Tundra. A lot of my heavy towing are in the Ozarks in N Arkansas. I needed a diesel to tackle those mountains with a load. If you don't NEED a diesel, don't get one. for all my day to day commuting I drive a 1990 Honda civic
