The Edge Evolutoion is a programmer.. It can change for tire size, remove the limitor & will over right the ECM. The Edge Juice with Attitude CTS modifies the signal from the computer. It does not change the ECM. The Juice is switch on the fly tuning. Meaning you do not need to turn of the truck you can move to a higher tuner on the go.. If you are worried about warranty the Juice with attitude is a better way to go then.
