Originally posted by jpgomez22 I just purchased a resistor that is suppose to add 5-20hp by replacing the IAT sensor. Does anyone know if this will work?
it doesn't do much except that it tricks the ECU into thinking it's all cold air that's coming in... thus u'll be running rich.... and will have a black muffler tip, and if you keep using it.. ur cat will be damaged. with this hack.. u'll feel like ur car has more power, but that's because it's giving more fuel.
if you want a better throttle response... just tighten the throttle cable up a bit. then u'll get the same feel as using that hack... and this won't damage ur cat.
