FS-ZE engine swap tuning question

I recently did an fs-ze swap in my p5 I had to use the original intake and exhaust manifolds and crank pulley from my old worn out fs-de just to get everything plugged up and so it would run with the usdm ecu without any check engine lights. Is it possible to have the stock ecu tuned to get the full potential out of this engine or do I need a stand alone unit?
