So I've recently purchased an 04 Tahoe with the unfortunate AWD system which kills gas mileage for me. I have already done a few things to work towards achieving over 20mpg per tank.
So far I've done
-clutch fan to OEM electric fans
-Roof rack delete
-75% grill block
-Blackbear performance tune (power and MPG gain)
-Full synthetic in the Front/Center/Rear Diffs, the transfer case, the engine and the transmission.

On the very near horizon
-05-06 Tahoe/Suburban lower Air Dam
-3/5 drop from Norcal SS

Thinking about doing
-Extend the lower air dam a little more
-Belly pan in areas that don't need access often
-Switch the lower bumper to the no towhook, no foglight version

Also changed how I drive quite a lot. I accelerate quicker and try and keep the engine under higher load lower RPM during accel, I keep speeds low and consistant and I throw it in neutral as Im approaching a stop light.

I've seen how extreme people get modding their cars for this stuff. I've basically reached my visual limit for mods.
