Best Mileage Mod

What mod in your opinion gave you the best MPG increase? (E-Fan, exhaust, chip, cold air intake, etc.)

I think an intake/airbox mod kills mileage because it's giving the engine more air for the same exhaust. ( this is if you have a stock exhaust ) More air means it's getting more fuel also probably.
I just put an e-fan on today, i'll see how it works for mpg in the next day or so and post.
I have a JET chip too, no change.

Larger heavier tires totally bring the mpg down the drain.

if i wanted gas mileage i would get these in this order..

KEEP OUT OF THE THROTTLE!! NOT PAST 2500k-3000k on shifts
leave stock tires
bamachips tuner/chip running 93
magnaflow exhaust
e-fan
air intake..

the best mpg i ever got was with...
32 inch tires, bamachip(93 octane), and stock air intake. i got 20.2 mpg with city driving once and averaged 19.3 mpg over several tanks.

Well guessing from you truck page you already have a tonneau, efan, and intake. the only other additions would be the programmer and exhaust.

What is your mileage now? Tire size?

#1 on my list would be a tonneau cover. But it's false economy...
you'd never save enough to pay for the purchase.

For hiway use, changing the 4.10 to a more reasonable ratio would also help.

Ahhh...You dont need no tonneau cover....just throw a whole sh*t load of fire wood in the back and drive highway. I delivered to my grandparents a load of wood and got 26.8 mpg over 160 miles. Best I've seen in my truck.

26.8 huh? No offense, but I think you should brush up on your math. I can't see fuel economy like that from our trucks...

Right now I'm getting 19.2 city/highway mixed. Tires are stock Goodyear Wrangler RTS, 245/75-R16 @36 PSI cold.
What PN Magnaflow are you guys running? I was thinking of getting the 9424512 SI (2.25) DO (2.00) and exiting in front of the rear tire.

fresh plugs help if you are not where you think you should be as far as mpg. Synthetic oils can help a little.

I agree, there is no way you are gonna get 26.8 mpg with a load in the back. The stock numbers for mpg don't even go that high. IF that number is true, that is the best number i have ever seen for mileage out of a 4.0L.

The best I got on my 3.0 was about 22, average was 18 and that was after intake, exhaust, tuner, 33's, maf mod.

Easiest thing to do is trade it in on a Toyota Prius if you want fuel mileage anymore.
