Tuner gets rid of torques management too. So you have a lots less downshifts from going into OD way too early

 

I've got the 360, from doing my own reasearch I came across the hypertech Econ, it sounds like what I need but I can't find any info on it, anyone use one? (Btw I don't really care about performance, I'm happy with how it is now speed wise, if I wanted something fast I'd get a v8 car, I just want it to be as fuel efficient as possible, however I know that it is a 4x4 truck so I shouldn't expect too much)

 

Answer is: you won't get better fuel economy from any tuner especially on our trucks. Again, what is your current mpg average? Most get 13 to 15 hwy and 9 around town! I used superchips and now have SCT, hypertech not gonna do it either.
