Default Besides AF and ignition timing, what else is there to tune?

What other parameters are there to tune when tuning for power (not drivability)? I went to the dyno and had lower than expected results, but I don't know what else to tune.

From my other post :

As you can see, all the motor runs were very consistent. 3 runs all motor and 3 runs with N2O. I am alittle upset that I only got 369RWHP when I was expecting closer to 400-410RWHP. I knew my car wasn't running as strong as 400RWHP from my track times, but I figured it was just that it needed some dyno tuning. As you can see from the graph, the AF is pretty solid, 12.8-13.1. The timing is all 29-30.5 as measured from Autotap. I have everything worked out, I was ready to tune, but I didn't see any where that needed it. Maybe I could take away some fuel below 4k rpm, but I was more concerned with the peak power. The graph looks good, just about 30-40RWHP low.

Anyone? Those with LS1 Edits, what parameters do you actually tune? From the data I've shown so far, how much benefit in tuning would you guess I would get?

TTT I'm interested as-well. I and some friends have Edit and we are always experimenting with it. I would like to know if there are some basic guidlines to Performance Editing since the places doing the programing really don't change all that much.
