There are really only two ways to turn up a 7.3 powerstroke. One is with a programmer, the other is with a chip. A programmer removes the factory program and replaces it with a tuned one. A chip plugs into the computer, and then interrupts the signal from the computer and changes it. So with this being the case a chip will override the programmer.
It's not like a cummins which increases horsepower by turning up the fuel from the injection pump, and another box would turn up the timing.
On a powerstroke custom tunes are made that increase things like timing, and injector pulse width, and injector timing and so on.
