Are any of you with a Bully Dog or other ECU tube running colder plugs?

I'm running the original equipment type plugs with my mods and Superchips 93 performance tune with a 3 degree advance over stock on the timing. I wouldn't think you would need to run a colder plug unless you are doing something to increase the combustion temperatures significantly, i.e. via forced injection or doing something to the engine like shaving the heads or using higher compression pistons.
