New K&N filter, plugs, PCV valve, and fuel line filter just to be safe. I also started adding acetone to my gas at 3oz/10 gallons and my tire pressure is good as well.
Since doing all of this I have not seen any real increase in my mileage. Today it was still 19 on the highway. I don't drive hard and on the highway I travel from 65-68 mph @ 22-2300 RPM. I guess this mileage isn't bad but after seeing some of the others on here who are getting 17 in town and 23-24 on the highway I thought I may be able to get close to that as well. Does anyone have any other ideas to try?

BTW, isn't the Bravada AWD? That will affect the mileage a bit.
