Finally the response is still there. Soon a custom toon will be added for even more out of the ecotec 3 v8! Love the tuner.

I am up one mpg after one month of owning the range AFM disable and I also love the on demand power my Sierra was meant to put out. Not to mention this has also fixed a few hard shifting issues as well!! Thanks Range! Looks great too, has a cool looking blue light and looks very clean.

Overall great but doesn't work with the 8 spd trans. 2015 1500 Denali 6.2L. the workaround is to choose manual transmission in programming, but obviously you aren't getting any shift point adjustments or anything. Another note is that I have a lift and 35" tires, but the speed calibration had to be set to 33 to be accurate. "Luckily," we have the radar signs in our neighborhood, so I could take a few tries and get it dialed in, otherwise speedo would have read fast, not slow.
