Stacking programmers or chips?

[400exrider]

What exactly does stacking do. I know that it is using two programmers or chip. It seems to me that one would override the other. I'm not wanting to do it or anything....I am just curious as to was exactly is going on.

The main reason I was asking is because a buddy of mine used to have an 05 or 06 cummins which had some kind of programmers or chips stacked. I think it may have been an edge and a bullydog (I think it may have had crazy larry tunes or something like that). The only other thing it had was straight pipe and maybe an intake. And supposedly some of my other buddies think his may have been faster than my sct/innovative extr.race, straight pipe, intake f-250. So whats up with this cummins setup?

Which do ya'll would think will be faster?

Stacking does not work. Yes they will cancel each other.

Stacking on a .cummins is totally different than stacking on our 6.0Ls. There is no reason to stack on the 6.0L when you have a custom tunes SCT. I speak from experience on this. Stacking on the 6.0Ls is a NO NO!

I'm not wanting to do anything to my truck.... it runs to good. I'm just curious as to what it does on any vehicle. Could you elaborate on the cummins stacking?

I just like learning......I like knowing how stuff works and why it works.

You can stack on a CR cummins because the flash device and the module you choose to stack together can control different functions. For instance, if you run a smarty with a TS MP-8 the smarty can control the injection timing and fueling, and the MP-8 can control the rail pressure. This is an overly simplified example, but it gives you an idea.

You can technically stack on a 6.0, by loading up a programmer then using one that stays plugged in after. If you use to regular programmers they will cancel each other out... if any of this makes sense..

though it is a terrible idea.
