I was looking to pull the trigger on 06 1500 cc. 5.3 , and was wondering what you guys mpg #s were. I did a search and got #s for 6.0 4x4 and i have one of those. Looking to see if i should expect any bettermpg

 

Well, with my list of mods below, doing about 25%city/75%highway--I average about 18-19 mpg. I would get 20-21 mpg if it was 100%highway. Stock I averaged about 21-23 mpg and my best mileage stock on 3.42 gears was about 25 mpg on a trip
