PCM? You don't need a reflash.
You picked a good year. We can help you out. Start a post in Performance and Brainstorming, and let us know your goals and realistic budget.
Be prepared for alot of custom DIY work. The Series 1 doesn't have much VENDOR support, but alot of parts and possibilities exist.
