Well, show me the exact link. Unless they're replacing your ECU with a tuned ECU and its costing you several hundred dollars, its probably just a resistor. Some of the other members on this board are buying them for the few dollars they are offered for and testing them. It has to do with the air temperature reading, the cooler the air the denser the air and the better the engine will perform, hypothetically they're trying to fool the sensor into thinking the air is always frigid, so they always get the best tuned STOCK ECU map. I can't imagine there will be a huge increase in power, as the stock maps are for efficiency and reliability, not performance. Also, it hasn't been shown that it will even work yet, theres another post about this, you may want to look it up.
