How many MPG,s will i gain on 05 qc 4x4 with superchips tuner? If anyone has same truck and has added tuner please send me some feedback

 

I gained about 1 mpg highway and lost about 1 mpg city because of my heavy foot.

 

+1

The SuperChips programmer is a nice tool to have to read codes, or to change shift points, IMHO. I noticed little (1-2 maybe) MPG changes, but bought it to primarilly for the scanning capability and to stop the vehicle from shifting so slushy...

+100 on the heavier foot thing, as the addition of the K&N, Borla exhaust PLUS now having it shift firmer begs for me to stay in it harder and longer.
