Beat I could get going 75-80mph on kinda flat/hills in West Virginia
That's not a 7.3

No... I was just following and figured I'd share too. I really like the 7.3. I wonder if I made the wrong decision with the EPA crap. So I try and follow 7.3. Honestly, I'm thinking about building a race car and use itThat's not a 7.3
Wait a little longer to buy your crate engine. Ford will soon be offering the Megazilla version as a crate engine through Ford performance. They applied for patents last week.No...

WHAT IS YOUR GEAR RATIO - IM NOT DOING THAT WELL AT ALL!This was my post on another forums a couple of weeks ago...
Ok so I just did a mpg test on the new Tremor with 7.3L engine. Keep in mind these are on aggressive A/T tires. Mud terrains would yield worse results and road tires better. We drove two 50 mile stretches in Florida so no real hills and with minimal wind. First 50 miles cruise was set at 70mph. Second set of 50 miles was at 76mph. We stopped and filled up between and after each segment to get an accurate reading. This is an F350.
At 70mph we got 14.6mpg
At 76mph we got 13.5mpg
Hope this helps!

Still working on the BUILD ... so no pics yet ...Yes, it is a TREMOR w/ the 4.30 and that is the worst on the mileage - but took a RT from NC to Erie, PA, and only ave 11 mpg. Towed a 4300 lb car one way and the open trailer back ...
It makes me laugh to think back to older trucks. Years ago I had a chevy 1500 with 350 sbc. It was hard to start in winter. Rode like a tank. Regular cab (no storage), crank windows and got 9 mpg at best.I'm averging 15 MPG tank over tank, This thing does so much better than trucks from some years ago that I can hardly believe it.
The 10spd has made a big difference for sure. In the gas engine world N/V (engine speed over vehicle speed) is a huge metric for mapping economy within the OEMs. You're correct if you compare all differences like smaller tires with smaller (numerical) final drive things tend to balance out. All things being equal if you compare the exact same truck with a 4.30 and 3.73 final drive the latter will get better fuel economy, especially at unloaded steady state cruise. This is, of course, assuming the engine has sufficient torque, which is the case with the 7.3. You don't get a different set of gears in the trans Tremor vs. non-Tremor so that is common regardless. Dual-equal VCT in combination with an ETB will only be able to compensate so much. With a bit lower rpm, but equal work required, the strategy will have more ability to keep the throttle plate open to help minimize pumping work.People keep mentioning the 4.30 gears as the reason for poor mileage. I disagree. It's the overall gearing that counts and the work being done. 35" tires and .63 transmission 10th gear ratio make up for the 4.30 gears and give an overall ratio that is perfect. The variable valve timing tries to optimize the engine efficiency over a wide RPM range. I'm averging 15 MPG tank over tank, with a light load in the rear, relatively easy driving and tires set to about 50 PSI. This thing does so much better than trucks from some years ago that I can hardly believe it. 4.30 gears are perfect and make a real difference when towing or for overall drivability. In my Ram Cummins, I changed the gears from 3.42 to 4.10. It seriously improved how the truck drove and I saw no decrease in mileage. If for some reason I ever had to get another Godzilla Super Duty, I would insist on getting 4.30 gears.
That's outstanding. I've not seen that in my truck, ever.People keep mentioning the 4.30 gears as the reason for poor mileage. I disagree.

Why haven't you mentioned what engine you have??????Just returned from a 2,000ish mile round trip from Texas to Colorado towing about 11,000 pounds on a 25ft gooseneck and averaged 8.1 per the truck. That included climbing 3-4 mountain passes and lots of 75-80mph running across Texas. I was extremely happy with the trucks performance.
