How much did the 4.56 gears change your gas mileage?

Stock 3.55 gears, stock tune:
10.5 mpg around town
low 14's on the highway
towing 6000 lbs was 7.8 mpg (900 mile round trip over several mountain ranges)

Stock 3.55 gears, intake, exhaust, XCal / Troyer tune:
12.5 mpg around town
as high as low 16's on the highway
towing 6000 lbs was 10.5 mpg

4.56 gears, intake, exhaust, XCal / Troyer tune:
12 around town
max low 14's on the highway
towing 6k is still around 10.5 mpg, but a lot less stressful doing it.

I'm generally happier with it *everywhere* driving with the 4.55 gears. Towing difference is huge, but even just city driving is a lot more pleasant. But the tune definitely had the largest positive impact on MPG.

These numbers are all calculated BTW.

If you're asking me they're just ebay specials. Black lightning style.
