Is there a stackable program for cummins?

I know of an 03 truck that is running an Edge Hot Juice with the Predator. I thought I was told he is running the standard 160hp tune. I just loaded that tune into my 04.5 with the HOT Juice, and I can't turn the Juice up very far due to timing rattle.

The Predator has stack tunes designed to be used with our PowerPuck, not sure how it would work with any other units as we have not tested with them.

Thanks

So what does the stack programming do? reduce timing, duration, both? Just trying to get a handle on what the differnce is because I loaded the stackable extreme and it gave me just as much timing rattle as the standard program did.
