You don't "tune" the PCM for nitrous. You tune the PCM for max performance without nitrous - mainly, adjust ignition timing and A/F ratio. Then when you spray, you use external means to retard the timing (retard box like the MSD Digital-6) and adjust the nitrous and fuel jetting to control the A/F ratio. You may need different plugs, plug gap or even different injectors (dry system only).
