changed the egr valve and i'm getting about 11.5 now and when you take in affect my tire size is off throwing off the mileage gives me just a hair under 13 average ... which is pretty good imo considering .. i don't get much better on the hw though

Filled up today. 14.96.
Was actually happy about that. Need higher standards.

Mods in the signature line.....on 91 tune I get about 17.5-18.0 MPG mostly highway and some babying in the city. But I can quickly drop it to 14 by REALLY getting on the highway!

I am running 3.21 gears still, which really helps on the highway. I cruise 65 mph at 1500 rpm in mds all day!

my rpm is super low on the highway too but i kick out of mds/over-drive fairly easy with any grade or whatever with my 37's lol

My 04 4.7L was worse than that. Best I ever got was about 14.5 highway, with 3.92 gears and 4.56 gears. That engine is a dog in the QC, and it was even 2wd!
