I wouldn't recommend tuning your own car unless you are confident in your own abilities. Since you're asking such a general question like "I need some advise on tuning" rather than something very specific like "what should my max WDC be at 5000rpm with so-and-so mods?", I have to assume you don't have the knowledge and/or skills to be tuning your own car.
See if you can talk a local tuner into using the Openecu stuff to tune your car. Someone familiar with Streettuner or Ecutek should recognize most of it, besides the lack of realtime maps of AP, and the different interface. The maps are the same, though.
There are pretty much no staged maps out there, yet.
