Hi,

Anybody seen, or used, one of these:

Its a Magnum Oxygen Sensor Performance Chip - if the claims are to be believed its a bargain, at $30 - but what is the down-side?

Sounds to good to be true to me also. The downside is your wallet will be lighter, if it doesn't do anything, or worse if it does. The upside is it does what it claims, for $30 I doubt it myself. That being said, I use a Techlusion on mine and I love it.

Fools Gold....what it does is offsets the output of the O2 sensor in the presence of oxygen making the mixture a bit richer.....10 hp in their dreams. There is another gizmo that changes the resistance of the temperature sensor in the airbox, also enrichening the mixture slightly.....like on a cool morning, also $30 but returns 15 hp....that's a better deal......Yeah right.

If you have $25 to spare send it to me and I'll give you a resistor to do the same thing........castles in the air......
