Thanks for the replies, gentlemen. I assumed that if it really worked I would have heard by now on this list.

With only a two-wire connection to the Temp-I sensor (they call it IAT, or intake air temp) it cannot possibly have the adaptive behavior that they claim for it, and there's no way on earth it could "reprogram" the ECU.  It tells a little fib to the ECU about the intake temperature, and G-force tells you a big fat barefaced lie so they can sell you two dollars worth of parts (otherwise known as a resistor in disguise and a couple wires) for $60.  Disgusting...and their so-called explanation about stoichiometric mixture (great word) neglects to mention that every vehicle with a catalytic convertor has its mixture controlled at stoich (courtesy of the oxygen sensor(s)) because the CAT won't work properly otherwise.  Feh.
