You have to go into special fuctions, disable the DRL's, and then exit from special functions before it will work. But after that I was able to turn them on and off whenever I felt like it (on the fly) just by changing the setting.
I concur, I presently am doing the same on my truck with the Bully Dog GT Hemi +
