Autotune is only for PCV. I dont think PCIII has access to one. So you'll be on your own or dealing with a tuner. I doubt you'll burn a valve but you probably wont get the best map possible on your own. Even when you are doing some manual tuning.
225 seems high. I think you can get a used PC3 for less secondhand. I dont know if they made a PCV for the 03/04, you'd have to look.
Also careful with the danmoto exhaust. I'm getting rid of mine because its not meant for my year, but I've heard theyre risky.
