I just installed the edge evolution on my 5.3L 07 yukon. I have only run the economy mode so far and as far as i can tell, under normal driving, the truck is running consistently in the high teens and low twenties for fuel economy per the DIC. This is a major improvement over previous which placed the fuel ecomony in the mid to low teens. On the flip side, the truck is now a beast. I have not done much to test the performance but I've noticed that the pick-up on the highway is now ridiculously faster. However, please note the fuel ecomony went to sh*t when I got on it like that ,as expected. The installation was a breeze, taking about 10 easy minutes.
I bought this from SMM performance (gosmm.com). The guys at SMM beat everyones price by $25 ($375 with shipping). They were great communicators and kept me in the loop with regard to shipping etc. I would recommend them for other purchases.
