I'm new to ecomodding anything, but my recent purchase of a 2004 AWD 5.3 Tahoe has me looking for ways to get over 20mpg per tank. It's rated at 13/14/17. I'm currently tuned for and running 93oct e10-e15.

I've changed my driving habits quite a lot... I do 50 most of the time, minimize my idle time, put the trans in neutral when coming up to stop signs and slowing down, accellerate quickly keeping rpm below 3k, load around 40% and keeping AFR as lean as the tune allows during accel(14.2).

Here's what I've done
-BlackBear Performance ECU tune (horsepower and mpg)
-OEM 05-06 Tahoe/Suburban front air dam
-Roof rack delete
-Synthetics in Front/Rear diff, trans, engine and transfer case
-OEM 05 Electric fan conversion
-75% grill block

I haven't really been trying/modding for gas mileage until very recently. That's why I joined this site to get the last 2-3mpg of my 20mpg goal.

On the very near horizon
-3" front 5" rear drop
-LED lights conversion
-Getting the ECU retuned again with better shift points and leaner cruise AFR
-Coroplast or aluminum bellypan

Ideas are welcome. Just as a heads up I'm near my limit for visual mods.
