Got an update.
I gotta say, I am pretty happy with the SuperChips.. I have noticed that I can get up a hill on the highway and the truck doesn't need to downshift to keep its current speed (this used to bother me.. ALOT). Also, I think I'm getting slightly better MPG.. I haven't filled up yet but from what my averages tell me on my HUD, its looking like maybe .5 to 1.5 better MPG.
Added power is nice too!
