I had an Edge, just changed to SCT. The Edge is great if you are not going to DPF delete the truck. It's monitors and custom look are better than any other vendor. The horsepower gain is only 70 in the extreme setting. In the mileage and towing tune you will see a one to two mpg improvement. The Edge does not reprogram your computer, it modifies the signal on the way out of the trucks computer. By just modifying the signal it leaves no tracks for any dealer problems with warranty.
If you want a used Juice with attitude - six months - pm me.
