question about possible chipping my car

Hi,
I've seen at ebay car chips that say it would increase 20HP INTAKE SENSOR CHIP.
These are low cost chips.. about 10USD each..
My question is.. will it realy work?

Are you talking about the ones that mess with the IAT sensor? All they do is trick your car into thinking that it's still cold so it'll run richer and take more air in. You'd get more power improvement by chaning your spark plugs and advancing your timing 2 degrees. Richard
