Anyone running 3.73 or 4.10? If so, what kind of mileage could I expect?

I'm running 3.73s and my mileage around town actually increased a little bit, but highway mileage dropped a bit. You really won't notice a huge mpgs difference with a gear change. People like to really exaggerate about that.
2003 P71: Totaled, parted out, scrapped.
2003 P71: 5.4L swap, exhaust, dyno tune, stuff.
2002 P71: Stock.
Got a 05 P71 with 3L55 and I lose milage when I take the highway to work (best 21.2MPG) and gain on back roads (23.8MPG). The drive is 61 miles a day. Just check milage when I fill once a week then I take the other route and its always the same.
E85 is green and I dont care. But its also 105 octane = 7300RPM shift point and I really care.
Depending how fast you're driving and whether you've gone beyond your powerband in the RPM range, yeah, that makes sense.
My 05 stang was the same way. If I curbed my speed to under 65 I was fine (NY speed limits with sh!t roads deems slower driving speeds), if I took the car out to Jersey or on long trips like our meet down in Georgia doing over 65 mph ......steady 75 - 80 mph most of the time...........I'd eat fuel faster.
If you're highway driving is putting you well over 2200 rpm and you're concerned about gas.....gear down. That's why most of our cars come with the 3.27 gearing. The 3.55's are a great light to light gear in my opinion. But again, that's just my opinion from my personal experiences with my mustang.

I want 4:11s as Cracker only goes about 1/4 to 1 mile at a time. I bet that would help my gas mileage.
