First off, I'd like to say im really not sure whether this is true or not.. just thought id ask. My buddy is sellin a nintendo ds in good shape for 35 bux and im gonna buy it just to try them out. Figure if i dont like it i can sell it easy. Anyway, he was sayin somethin about i might be able to tune my car when i get it turbo'd using the DS and some program. Is this even possible? Is it worth it? Again, I heard this and I had no idea but idk i thought id ask.
