All it does it tricks the computer into thinking the intake air is colder.
So it runs a degree or 2 more timing.
You'll get the same affect by advancing the timing with the dizzy.

Once the resistor is installed and reprogrammed the ECU which is just a play with the fuses, the ECU will read that the air coming in through the intake is cold air; think of it as a "default" setting on the ECU. When the ECU reads this, it lean out the air/fuel mixture-in other words, it will take in more air, and then add more fuel

ahhh if the engine thinks the air is cold and its really hot and adjusts the ignition timing to suit... tick tick boom???
so this thing makes it lean out the a/f mixtures but it makes the engine add more fuel????
how does an engine add more air when the only thing that regulates the air intake of the motor is the throttle???
sounds fishy to me

It would work on a stock engine. Most engines are tuned a little rich from the factory to make them last a little longer at the expense of power. The resistor will ust trick the ecu to advance timing and lean the mixtures a bit I think. Would be safe if you didn't get silly.
It's just the same as playing with the springs on vane AFM's and like SAFC's I think, just tricking the ECU to use a different part of the map.
The actual performance gain would depend on your engine, if you had a remapped ecu then it would have no effect, as it would already be tuned for max power. I've read in a few places that you can gain 15HP at the wheels on the 5.7 LS1 by altering the AFM, just because factory ecu runs well on the safe side. in an engine like that it would have the most effect.
