Very user friendly device. I did see a 1.2mpg increase and felt a slight power increase also. I did the 93 octane tune. What I like best is I was able to turn off that AWFUL AFM GM uses on their trucks, now it's in V-8 mode all the time, no more of that dull sound out of the loud pipes when in v-4 or v-6 mode. I also increased the shift firmness, definitely chirpped tires a few times when I had to really get on it lol. Only wish the touch screen was more repsonsive.

Main reason for my purchase was to give my 2007 Chevy Avalanche a little kick when either accelerating from a dead stop or getting onto a freeway. Being only a 4 speed, I noticed my Avalanche "lagged", for a lack of a better word, when getting onto a freeway and trying to accelerate to freeway speeds. I wasn't expecting a huge boost, but I definitely noticed an increase in power when I put the pedal down. Fuel economy stayed the same if not increased, highly recommend this product.
