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.
