the Power FCs are great tuning devices that are simple to use, on a stock engine gains are minimal. if you were running a honda k-series like some european elises,gains are far more substantial do to honda's factory choked engine. as far as a header, i think DC sport would be a serious downgrade in performance over the stock one, anthing that will make noticable increased power is going to most likely custom made at this point with large primaries and a beefy collector. smsp and hytech make great number, their custom headers start around a thousand and take a few months.
