The following are items that CAN be stacked with a T Dog. However, due to the levels of timing and pressure in the T Dog this can be hard on parts. We have made excellent power using various combinations including the T Dog. Just keep in mind that when stacking, the exact levels/settings of the boxes/tuners must be adjusted according to what is stacked.
Timing/Duration Boxes
TST
Van Aaken
Juice (Not high on my list)
plus a few others
Pressure Boxes
TS MP-8 (My choice due to ability to fine tune)
Edge EZ (only a few settings, just keep it turned down low)
Dr. Performance Predator Module (less choices for tuning, but it still works)
There are others but the above is a good place to start.
With you already having the T Dog I would suggest a TST with adjustable timing and a TS MP-8
Just set the TST LOW and the Mp-8 somewhere around 30-40%
The rest just depends on what else you have done to your truck and if you have the modifications needed to porperly utilize the stack.
Good luck.
