better fuel economy

[felixgun]

sorry...but we get it over in the tundra world also...its kinda funny...

"i just installed this 6 inch lift and 37 inch tires and im only getting 12mpg" they even go back to the dealership and have them run diagnostics on it over and over because they arent getting 20mpg out of a 381hp truck....im getting an avg of 14.0 and am happy with it because i knew it going in.

I have factory 22s and get 14.1 mpg... my z71 nbs tahoe got 10mpg with 285 goodyear wrangler M/T's on factory 17 oem rims

Ok, so it's been established mileage is gonna suck either way....big ass engines in big trucks do that....but what can you do to improve it a little bit? That's also a valid question, because there are answers.

So there.

Here are some tips:

-CAI If you aren't trying to be Jeff Gordon, it can actually help.
-Free-flow exhaust: Same as above
-Clean your MAF and Throttle Body regularly
-Run 4oz of 2-cycle oil in each tank of gas
-Get a professional tune
-Do an engine swap with a VW
-Drive like a granny, and only down hills.

None of these things, other than the last two, are going to give you more than 1-2mpg gains, though, so don't expect a miracle.

I've found that no matter how I drive I get between 13 and 14 mpg in city and around 17 highway.

So after I sift through all the B.S. and smart remarks, I get:

CAI
get it tuned
and exhaust.

Thanks to those that actually tried to help rather than be a smart a$$.

Thats exactly what i have noticed also. My mpg city is 12 and 17-18 hwy.
Thanks for the info!

Yes, those three together should yield the results you want with the tune being the MOST important part of that equation. Just a CAI and exhaust will yield negligible gains...

Also gears for the rear end since you have those big 22s. It may make the most difference.

What's a good gear to go to with a 32in diameter tire? I think a 285/45/22 is 32.7in.

Will any of those hand held tuners work? I know its a basic tune but what has worked and what is proven? I know mpg is going to be different from person to person. Im really concerned with ease of use and quality.

Thanks!

Do NOT waste your money on a handheld tuner. You'll spend money and see little return. Go with a Black Bear Tune and you'll see an immediate difference! It's virtually the only way to go to get the most bang for your buck.

Either blackbear or find someone around you that tunes these motors and have them ride with you and they will tune it that way.

But if you go with gears and cai and such you may want to wait and get those done first then get the tune. People say you can tell them what you are going to get and they will set it up for that. But id do everything else then go the tune done. Just my opinion.

^^^x2 on the advice of doing the tune last after the others are complete....
