'01 GMC Sierra 1500 is worthless

I needed a break from my Honda so I started trying to up the FE in my GMC Sierra 1500.

This thing is a fuel hungry monster. I have tried all the easy mods and have had no luck

I can drive this thing like a "Bat out of Hell" or like a grandma going to church and it gets the exact same mileage.

Anyone have any suggestions for this beast???
