no you are fine leaving everything as is for the time being, if you do decide to mod your car anymore a higher pressure fpr and better flowing injectors would be a good idea

Go to a U-Pull junkyard and look for a n/a 16v 900. If it's still on there grab the fpr off of it. The yard charged me $4 for it when I got mine.

To run the 'redbox' level of APC modification the fuel pressure regulator needs changing to a 3bar unit. It is also beneficial to change the vacuum capsule to that used on the LPT (though I don't that was available in the States).
