Next step would be 550cc injectors and a MY97/98 2.4bar MAP sensor (if you have the ESL Live or Simtek). If you have an Apexi PFC, then you'll need it's own bespoke 3bar MAP sensor (avaiable in a complete Apexi boost control kit which also includes its own 3-port BCS).

Then you'll be able to run the 550s mapped at at least 1.35bar boost pressure, which will easily get you over the 300bhp mark - prob 320-330. :)

If you have deeper pockets, then fork out for a Hybrid GT Spec FMIC and large cone filter for even more airflow/safer runniing intake temps - heatsoak issues of the std TMIC will be done away with - for even more power e.g. this side of 350bhp and similar torque. I would personally stop at about 330bhp/330lb ft, for fear of the torque trashing your 13+ year-old gearbox! :)
