2010 silverado gear swap results
truck is a stock 2010 4x2 crew cab XFE with a 5.3/A6, lowered on 22s, bed cover
stock gear was a 3.08
driving to work and for the first 5 months of owning the truck i got 18.5 mpg, the drive consists of some stop and go and alot of 50-60mph driving
i recently installed some 3.90 gears
the same drive to work netted me 24.5 mpg on 87 octane! I have tuned the truck with Hptuners to optimize the active displacement. I also tuned the A6, removed the TM and zeroed the converter slip, a handful of other changes. the truck cruises effortlessly in V4 mode.
ill continue to test results this week and see how it does, i expected it to fall in the 22mpg range. 24mpg was a shock,
hope this helps anyone deciding on changing some gears. i really only changed them to help tow my camaro.

IMO, the average from one trip isn't really a comparison to a 5-month average. Run it for at least a month and it'll probably drop down a little. Your guess at 22mpg or lower is probably closer to the real average.
Still, great results.

Wow pull hills in V4 ........ can you elaborate on the afm tuning ?? ........do you think the gear swap also helps the truck stay in V4 ?
What cruise rpm to you get your best mileage at ? Towing with my old 5.3 truck it liked 2200 below that towing mileage fell off .trying to decide between 3.90's & 4.10's for my 2010 or tow in 5th withthe 3.42's
