just wondering if i should stack it or should i leave it alone. stack with edge ez or quad.

 

I'm leaving mine alone. I like the way it runs, and I think it does plenty on its own. I'm not looking to eek every last horse out of my truck though, so your mileage may vary. Only way I'd change my mind is if I ran across a screaming deal on a smarty. I don't know that the smarty runs any better than the predator, but the diablosport customer service blows. Smarty beats em on that account, hands down.

 

i have mine stacked with a vanaaken 3.2.i like that stack but it doesnt gain as much as from a stock truck.like said above the pred does a great job on its own.

 

The non stacker has lots of timing/duration along with pressure added the difference in the stacker is their is less timing/duration. Be carefull what you stack it with b/c they dont really tell you exactly how much of what is in the tunes and their tech support is something to be desired seeing how they never have the same answer from tech to tech, I was told one story by mike and called back an hour later b/c he never called back about the tsb question I had and he picked up the phone and I asked for johan and I asked johan about what I asked mike and he said no, no, no, no, no the hemi is my top pryority dont look for those options too soon in the future, nor does johan seem to show any concern for us cummins guys but hemi look out.
