I have been using the TST powermaxx and diablosport predator stacked. Obviously, I don't have either of the programmers on a high setting. I get a little bit of smoke. I would have to say that for the money the predator does pretty good. The only problem with using programmers, is that you want to try others after you have them. If you like to tinker with settings, EFI Live would be good. There are many people that use it and would share their tune with you. I have heard nothing about good things from PPE's programmers. It comes down to how much you want to spend.
