2010 Silverado 4x4, 5.3L 6spd Auto 3.08 gears.
Stock with 265's = AVG 17.6 to 18.1 MPG
2" RC level kit and 285's = AVG 14.1 - 16.5 MPG.
It's normally around 15.5 and I drive with a light foot. I have found anything over 60 mph and the gas mileage drops big time!!!
Next item is the H/T speedo cali. Oh and these are based on 70% highway

2009 Silverado 5.3, Z71, leveled, 285-65-18's. Catback exhaust, decent air filter no intake though. city(small town 45mph):13mpg's stop and go.
Highway 60-75mph driving like a sensible person not using cruise in the hills and rolling on and off throttle to coast up hills(not lying here):17-21mpg's.
Your right foot is the biggest mpg factor, no matter how many upgrades and programmers your foot controls it all!

09 Sierra 4x4 5.3, leveled with 275/55/20 wheels and a flowmaster SI/DO exhaust. I get 14.5-15.1 City (depends how heavy my foot is). I drove nearly exclusively in stop and go small town conditions. I'm not sure what highway mileage is since I never take trips over 15 miles. Not too horrible for such a bulky aggressive vehicle.09 Sierra SLT
