Henrik D from Carlsbad, CA said, "The superchips programmer lets you re-program your car withy ease just plug it in and follow the screen prompts.in less than 5 minutes you have programmed your car to run at 87 octane with almost no loss in power on the rear wheels.However you get the best milage running it at 91 octane or higher. The 87 octante setting gives you the best milage, but again running it at higher octane gives you even better milage. my Nvaigator went from 13.8 to 23.9 in the XS mode. running at 91 octane. power at the rear wheels 318 hp.the programmer is worth its money !! big times.missing: ability to program a navigator 2007missing: ability to programming odb1 Towncar 1993"
