My wife and I loved the Protege5 so much, we drove over 250 miles one way just to buy one. If that wasn't shocking enough to me, she said she wanted me to do some mods to get more power out of it. I know a turbo, supercharger, or cat back is the best, but that is too much. I wanted to know what people have done for under $100 to get more power. What is the best low price performance item? Are there any ideas that can get me better economy(or not drop any) and get me better HP?
