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.
