I was on ebay, and there is this guy selling so-called "Modchips" for all different breeds of autos. He had one for the alero. He says it will add 15+ horsepower. Now i'm sure this is probably some little wire or diode you slap onto something under the hood but i'm curious if anyone has purchased one of these or knows what it is and how it's done? the thing costs 5 bucks on ebay. let me know!
