If you have it wired through the upfitter switches, it won't matter a lick what tune your running on the computer. All I have to do is put my parking brake on, flip switch number 4 and off it goes to about 1200 rpm. If I want it to stop, I just press the brake pedal and it goes back to normal for a few seconds unless I either put it in gear or take the parking brake off or flip the switch. Works on any one of the tunes that I have(another reason to have it seperate from the programmer, you don't have to remember to switch for each one).
