I'll bite...let me guess its an intake air temperature sensor (iat) signal modifier that you splice into the sensors wires and it lies to your computer to change fuel and timing? If that's it I've never used one or known anyone that has. If it worked that well i would think the big name companies would already have a similar program for there canned tunes.
