That would be "instead" of an SCT or Diablo tuner. You need to make a choice. Jet and some others make a plug in module such as this but the gains are equal to the money spent it looks like to me. Plus you cannot modify the parameters since they are built into the module to intercept the factory programming and send their own signals.

An inexpensive mod but cannot be modified as the more expensive ones can.

 

actually, this looks like one of those piece o crap resistor things you put in line with your MAF to fool your car into thinking it's getting more air than it actually is...

then the car sends more gas (thinking there is more air)... and you might get a little more power... you'll also run a lot richer, and could end up with detonation problems...

granted, I could be wrong, but that thing doesn't look like a tuner module. It's only got 4 wires, which I assume is to splice into the wires going to the MAF...
