Who knows your car might run a little smoother--->you drive a bit more relaxed-->slightly better fuel economy.

The first piece of equipment you should buy is a ScanGauge or an UltraGauge: once it's calibrated you won't have to think you got a difference in mpgs, you'll actually know what you're getting. That's critical, because as iikhod alluded to, your right foot is where the biggest improvements are. But the overall sloppiness of SUV efficiency can't be ignored. You can work on aero and tires to get some impressive % gains in mpg. As to tires... what psi are you running, and are you taking their diameter into account when calculating your distance traveled?

As it is, any increases in combustion efficiency that an extra (see?, I didn't say upgrade) fuel filter may bring are going to be more than counteracted by your other mods that increase the amount of gas being squirted into the cylinders: the CAI and throttle body. The 4.0 has enough power to move the rig. Throwing extra gas into it isn't very good for increasing your mpg. If "efficiency" means towing a boat up a mountain quickly, then by all means, shove more gas into those cylinders and get as close to perfect combustion as you can. If you want to improve your mpg, find a stock throttle body and while tearing out the CAI, think about designing a warm air intake.

But if you're not going to get a ScanGauge or UltraGauge, at least get a Fuel Shark.
I really like ecomodder--it has helped me a lot. I've toyed with the idea of buying a scangauge for a while now. I suppose that should be the next thing I buy. It is hard to see the difference in some mods with the normal variations in tanks. For example, last tank I got over 17 mpg, but this one it looks like I will get at least 19 mpg (though it is warmer outside). I did see an improvement with the throttle body and CAI, but like you are implying, it is hard to know without the scangauge.

My tires I run at 34 psi. I've seen a lot of people recommending to run them at max psi, but is no one worried about uneven tire wear? Although the max psi on my tires is 60 psi... I'm not sure if I want to have them that high. My tires are getting old though so I will try bumping it up a little. I do take my larger tires into consideration... I need to multiply my miles by 1.04 for an accurate reading.

Hopefully I have a scangauge before I install the fuel filter. Most people here value mods when they are validated with a scangauge.
