You said "gas" mileage so I am assuming your 2008 Chevrolet Silverado has a gas engine, not a diesel. 24,7 miles per gallon for a full size 3/4 ton pick-up does not sound to bad. Do you recall what the EPA estimate on the window sticker was?

I have 2004 Duramax and the fuel mileage SUCKS!! 12 or so towing and 14.5 regular, spent $500. for super chip,$500. for larger exhaust and K&N air filter. Very disappointed.
