Okay, so with the gas prices rising, I've been looking into putting a performance chip into my 02 Protege. I found this one on eBay for $23 (nevermind that the auction has ended, I'm sure it will be relisted), but since I know absolutely nothing about the car's inner workings, I don't know if it's a scam or not.
The description for the item is quite extensive, but I have no idea what half of the stuff in there mean. Can anybody advise if this will actually improve my mileage and performance?
