Any ways , what are you running? You know type of car and motor, timimg maybe.



You can buy a pretty cheap air/fuel monitor for cheap from Summit, about 125 dollars the last time I bought one.

Even cheaper but just as good ,maybe better, you can make your own. You will need to get a O2 sensor bung (5 dollars) and get it welded into you exhaust (20 bucks). Then get a O2 sensor (65 dollars) plug in some 12 volt power and the other wires go to your volt meter and thats it. One thing to keep in mind though is if you are running headers you need a heated 02 sensor . For anything running a 02 sensor and headers the sensor need to be heated. A heated 02 sensor will give you consistant results since the tubing of the headers are thin. The exhaust will cool down quicker and give false readings .

If you have a newer system and have a 02 sensor in the vehicle just plug in your volt meter.
