How does one tune for efficiency? I have yet to hook up my Powrtuner (keyspan is on the way), but I just got access to their forum. If anyone has any links, or guides, or helpful tips on how I would go about this I would much appreciate it.

I am a beginner in tuning, though I already understand a lot of the concepts. I learn quick so feel free to throw it at me and I'll go with the learning curve.
