QuadsBC's 05 Double Cab Tundra Family Expo Build

I'd think that higher elevation would mean better gas mileage... less atmospheric pressure so less gas is added to the mix, right?

This is the up stream o2 sensor I got last time. It fits the Tundra as well.

And you want to replace the upstream. Downstream is only there to make sure your cat is working, upstream is the one that dictates your air/fuel ratio.

I didn't notice too much difference in other vehicles. I have only had the Tundra a month and it has not left the Denver Metro area yet. My 1996 4runner mileage didn't change on trips to Kansas, Utah, New Mexico or Arizona.

This is unrelated to your post but just saw you have 255/85r16 Maxx. Flyer69 on here was looking for pics of that tire size on a Tundra. Just crossed my mind when I saw your sig.

Not better mileage, the air density is lower, so you actually end up with less power. That's why turbocharged vehicles rule Pikes Peak. Your engine is an air pump, so still moves the same volume of air, it's just less dense. Same fuel, less power... That's the short answer.

Well, this thread made me want a DC FGT. But also made me realize how little to none ( i mean none) fab skills i have. Looks great

Replaced both my upstream a/f sensor last year and didn't notice any better mpg

All fuel mpg is done by the math compensating for tire size difference. Elevation is normally under 1000ft. If I use cruise control my mileage decreases. I don't normally use cruise control.

Yeppers. I second that. My old Ford Escape had significantly less power here in Denver than it did when I lived back near Boston. It got even more anemic in the hills and required a bit right foot to get around.

Here's a few of my 4 runner...

What bumper is that?

 

[QuadsBC]

What bumper is that?

Front: custom made (addicted off-road style, lower and tighter to the body)

Rear: custom made (4x4 labs style, again modified the way I wanted)

3 days in the back woods of Maine, just got back in. Here's a few from the trip to the abandoned trains.









More to come...

Just something awesome about having 3.5 million acres of woods to play in within just a few hours drive time.

Little disappointed in myself for taking so long to get up there. From what you read online everyone makes it sound like you enter there is a solid chance you won't return. In reality it wasn't like that at all. I purchased the app Gaia before going and that really helped with the navigation. We didn't waste as much time on dead end logging tracks. We did explore some that were dead ends although the map showed a through road. Gaia's aerial view is about 5 years old from what I can tell. I can't wait to get back up there!
