I've got a TST 3 box, and was curious about stacking the Edge EZ or comp to it. I know that you shouldn't stack the TST with the Superchips programer due to the timing problems. Any advice would be taken into consideration, and I know I need injectors, pusher pump, etc.

 

Many folk stack it w/ a Ez, but you can't stack it w/ the comp. You can leave the comp in ez mode (wire untapped) and have the adjustability of both worlds.

 

Pardon my ignorance but what exactly does the TST do?

 

the TST does basically the same thing as the Edge Comp, more power, go to http://www.tstproducts.com for more info

 

Stacking a timing box with the TST is a good move. You could stack it with an EZ, Diablo power puck, or a van aaken. My chose would be the Van Aaken though thats not what I currently have stack with my TST. I have my timing box hooked to the MAP and the the TST to the timing box. You'll notice bottom end improvement. You can cruise with the TST off and get a couple MPG improvement. I did anywho.

 

Sort of but not exactly.
The Edge Comp has timing added to the increased fueling.
The TST PM3 is a fueling box only....increases the amount of fuel based on boost level being generated....starts adding fuel at 3 psi boost.

Stacking an EZ or a Van Akken on a TST box is an excellent way to go....best of both worlds. Timing and early fueling from the EZ (on high with stock injectors)...Mid range & top end fueling from the TST. I love mine. More expensive than the Edge Comp, if you don't already have either box, but also more reliable, IMHO.

Stacking boxes has been around for a few years, with absolutely no negative side effects!
