Question Top Fuel Economy Mods

Calling all Tundra experts!!!!

Can someone please give me some realistic mods to improve gas mileage? Some concrete, this is how much I gained, mods that don't involve 600 dollar uni chips or ebay rip off chips? Thanks

Drive when theres no traffic and go easy on the gas pedal.
This is what I acheived doing so this morning at 3:00 am!!

And note that this is with 20x12 rims, 37'' tires and a 12'' lift.
I do have a pretty nice exhaust setup which did help a little bit and a volant intake.

But really though, its a truck. You cant expect much out of a truck for gas mileage unless you got a diesel with expensive mods added on.

Move your seat back so it's harder to reach your pedal therefore less likely to drive it hard.

im no tundra expert, but there is always a more efficient way to have any system operate

what makes tundras get less mileage, lets start there(dont pay attention to the obvious ones like the V8 and 4x4)

1. running bigger tires- is it because, there is more mass in the bigger wheel than stock?
maybe a lighter wheel may do the trick?
Or is it the size of the rim, going from a (17'' stock?) to a (20 aftermarket?)

2. bigger tires and tread pattern?

3. does lifting you truck- A. with suspension lift? B. body lift?

4. exhaust and intake systems- this is a question for the guys that have a dyno available- diameter of exhaust tubes? and X pipe V.S. Y Pipe system? and intake piping with a cone filter?

keep in mind folks, im just throwing these questions out there to organize the answers.

add more questions and theroys

I've heard bigger tires can help HWY mileage (but worse on the street due to taking more to get going) because they are heavier and hold momentum better. On the other side you need a lift to get the bigger tires so the areo is messed up
Not stating a tested fact just what I herd or read a while back

I have plans for K&N CAI and Exhaust to improve power and air flow which sometimes translates into better fuel economy.... If I could just get an increase of 3-5 mpg I would be happy.

I had the drop in filter and now back to stock. For one it lets too much dirt in and two I'm pretty sure I got worse mpg.

I Think its all in the gears.The 6 bangers get a 410,and big V8 get a 430.Chevy which 4.8 has a 340 and 4K max towing.It get 24mpg but it can't pull nothing worth having.Its a car with a truck coustome on.I asked several people with chevy's and the 6L which I need gets a 411 and about 10mpg.I have a friend with a chevy diesel and he asked for the high rear end 308 he says he get good milage,but it falls of alot if he pulls.Ithink yota put some thought in this and get the best of both worlds.
