Not cheap to get there, but it can be done.

So what is the list of mods? I have an 03.

Intake: +20hp to 25hp depending if you go full intake mod.
Exhaust: +15hp cats on headers, cat delete pipes and a proper muffler.
UDP: +5hp
Tune: +15hp

On the low side 55hp increase the 2003 Boxster S 258hp = 313hp.

???What? You can't add hp by each mod. It doesn't work that way
