Once you pull the log in you'll want to look at timing, generally speaking if it is advancing in a linear fashion throughout the rev range and relatively consistent across cylinders.
You'll want to look at your HPFP to make sure it's keeping up. Any prolonged dips under 1500 psi are not great.
Check out your boost as it compares to mass air pressure. If you are generating too much boost, the car will taper the throttle. If your car is reacting well to the map your MAP and boost should be running in lock-step (or mostly)
Keep an eye on your knock sensor. Intermittent low RPM knocks are ok, but frequent higher RPM knocks could mean poor quality fuel or need to change/re-gap your spark plugs.
Those are the main things. The most important thing is consistent timing and linear timing advance with no knocks (i.e. pre-detonation). Strong, consistent timing = good clean power.
