    Default New Vortec Max

    On the 07 and up Vmax, any suggestions on tuners, and how in the hell do you get rid of the speed governor??!! 98 mph isnt working.

    pretty much any programmer will remove the top speed limiter, and theres several different ones that will work on your truck .the hypertech max energy is probably the cheapest and has all the functions of the other brands. plus they offer free updates online. i have one on my truck and havent had a minutes trouble out of it for over a year now. not to mention hp,torque,&mpg gains.
