My numbers are pretty inline from others ive spoken with. Mine are in a 1078. I was getting 5-6mpg prior. The old gears will kill these trucks at hwy speeds. Here is a photo of my gps showing 74 vs the tach. Ive hit 76mph but didnt get a photo with the tach.

Coachgeo have you ever driven a truck thats been re geared? Its a simple consideration of powerband. These engines make plenty of power.

I think you may be worried they dont have power for gears and tires. the fact is, These motors feel gutless because they are wrapped wayyyy out of their powerband with too high a gear for hwy. my truck feels at 65mph, how it did at 45mph before. The shift points have smoothed out considerably...

No. 225. I will be pumping it to 290hp soon however.

If one tire is one the ground, it will not move. Therefore no power can be transferred thru that side of the axle. Jacking up one tire will render the results needed.

Keith also has an A1 with a C7 cat. Perhaps his economy is due to that. my 3116 sees a bit over 6mpg with factory gears.

center section, center chunk, the differential portion of the axle. You know, the part you want to break land speed records in your lmtv :)

For anyone interested, i have an extra set of high speed third members for sale in the portland area. I can install as well, if you bring the truck to my shop. pm if interested!
