Just had a question: I've seen many ads in performance magazines for extra computer performance parts that are supposed to add 25% more horsepower, increase response time, and so forth. I was just wondering if these things actually work and which ones do. I was considering buying one because they look worth it but my dad said they are crap. Need some advice.

 

Wrong forum, and they do not work as advertised on a car such as yours. Listen to your father.
