i probably should of done that thanks!

 

my 08' 5.3 was getting avg 15.3
my 07 classic 4.8 is getting 18.1

 

Daily mixed driving my 05 Z71 Ext Cab 5.3 has been in the mid 14's through the winter, but last summer I was averaging above 16. I'm hoping it just the lower temps and winter gas and my mileage will return as temps rise.

 

14mpg avg in my 02 ecsb z71
16-17mpg avg in my 99 ecsb 2wd with mods in sig

 

There is something wrong with your tune then

 

Just to cheer y'all up my 87 crewcab is getting 6 around town. I can't hardly wait for the 5.34l6oe swap. Its on the stand. Jay

 

350 or 454??

 

14.8-15 just a CAI
