Tundra Chip/Programmer Help
 

Hey Guys.. I'm in need of some advice.. And (I KNOW THIS IS THE SITE FOR IT)!!! :D:D:D

I have a 2007 tundra 5.7L with a 3 inch lift .. I purchased the truck this way 2 yrs ago.. with 38,600 miles for 18K..

I was running some 295 70R 18 Nitto Terra Graps on it... Gas mileage was about 14 MPG.

Well It was time to get a new set of tires... SO I asked around and went with the Toyo All-Terrain Open Country 2's. But I downsides to 285 65 18's.

I'm running 52# of air in them. These are 10 ply and call for 80# max.

My mileage has gone down a little, about 275 for a tank... I'm not getting 300 miles to a tank for gas. :pissed::pissed::pissed:

So I'm thinking about getting a chip/programmer.

Question:: Will this help with gas mileage??? When I pull my Triton I'm getting 8 miles a gallon or about 200 miles a tank..

Anybody have a chip on a tundra??? What brand??? Can u install your self???

I was speaking to a few people at work and they are using chips on their F250's gas and diesel trucks.. And they say they work..

Other than the crappy gad mileage, I "like" my Tundra.

Please advise.. Im sure we have a few younger guys who are running lifts and bigger tires..

Thanks in Advance..

With ur tire change is ur speedo correct... Could be gettin same mpg just looks worse bc of tire size change..

First ,10 ply tires are typically for 3/4 ton and up , not for a 1/2 ton pick up , But since you have them you need to run the air pressure called for that tire . That will help .
Programmers for gas and diesels is apples and oranges . Diesels can gain massive HP and or small feul mileage depending on setting . Gas motors gain very little of either . I have both . Rough example = if you get one MPG gain , which you probably won't ,
One tank of fuel every two weeks , it will take two years to break even figuring the programmer cost at 350 . If you want fuel mileage buy a PRIUS:D

If you re-gear the truck, you should get closer to your stock mpg with some lower gears.
