    Are Superchips Really Super?Are Superchips Really Super?
    Although most automobile manufacturers try to achieve a balance between performance and emissions when the ECU is programmed, in reality more power can be obtained when certain engine control parameters are changed. Aftermarket superchips are made to adjust parameters to increase engine power and torque. The superchip gives a “boost” to your vehicle’s performance by enabling you to adjust the settings for the ECU, and allow more fuel to be injected than the factory settings provided.

    "I have owned the Cortex and this does the exact same thing. This one can only be used on one vehicle, that is the only difference. Woke my Denali right up, it has never run so good."

    "Installed in my 2011 Sierra with the custom dash mount, took about 20 min to get everything in and working. Very easy to install and looks great! Several custom tunes to choose from on the device, or go to Edge website and download others."

    "It got to my house quick; was easy to install, and allows for speedometer adjustment for tires! I had to read my speedo 10 miles faster than what it said before! Not anymore!"

    "The tuner wad easy to install but didn't make that big of a difference, a little horse power but nothing for fuel mileage so far."
