Bought a 2008 Armada LE 2WD w/ stock 20's. I added Superchips and CAI and documented my MPG's after 50 miles at different speeds and settings. Miles were documented traveling from Dallas to Houston.
93 Tune
20.1 @ 70mpg
19.8 @ 75mpg
17.4 @ 80mpg
91 Tune
17.4 @ 70mpg
15.7 @ 75mpg
15.5 @ 80mpg
XS Tune w/87 oct
18.1 @ 70mpg
17.6 @ 75mpg
16.1 @ 80mpg
The 87 Tune was very similar to the 91 Tune reading mpg at different speeds. I struggled making sense of this.
As for performance, the 87 Tune was drastically different from stock and I notice no difference with the higher octane tunes.
