ok, I was searching around on ebay and I came across this module...It supposedly gains 15+HP and 5-10 mpg gas. Sounds like a scam to me...No pics of what it is and it claims it adjusts your Air/fuel ratio. Claims cars run to rich on fuel so it adjusts it to make better gas mileage....Also claims with running lower air/fuel, will gain more horsepower which doesnt even make sense. Anyway, can anyone give some input on this?
