I figure I'll just post up the plots and then discuss them afterwards.
Here is the extended testing (250 miles to 8500 miles with 2 oil changes) with an ECU reset for curiosity's sake tossed in.

Here's just the ECU reset before/after:

All runs in 5th gear, on the same dyno (ours) and the same car obviously.
Runfile 10 represents the best pull on a fresh motor with 250 miles on the odo.
Runfile 17 represents the best pull on a broken in motor with 2500 miles on the odo and a fresh oil change
Runfile 21 & 22 were done today back to back at 8500 miles with no changes but fresh oil from runfile 17. It represents additional power from break-in at the 8500 mile mark
Runfile 23 represents a fresh ECU reset pull with ideal conditions (cold coolant, warm oil)
Runfile 24,25,26 represent a hot motor and were done with zero cooldown between pulls.
The second plot is just to give a good example of what a fresh ECU reset can do to the power plot.
We previously argued that the ECU is more like a toyota ECU in that it runs max timing on reset and slowly pulls back timing as knock is detected. Other's had made the claim that it is more like a subaru ECU in that it runs a dynamic advance multiplier below max and slowly adds timing back in.
With this dyno testing we can confidently say that the ECU runs max timing on the ECU rest.
Furthermore we can give advice for those seeking to have parts installed on their vehicle, and or tuning.
Based on our extended testing, we recommend not having the vehicle tuned until at least 2500 miles on the odo (and hard driving after the first 500 break-in miles.)
We also recommend, prior to dyno testing/tuning, to reset the ecu get a baseline pull or 3, install parts, reset the ecu again and do the final after dyno.
Doing it in this way will eliminate any power gains from an ecu reset and show just what the parts will make.
Not doing it in this way enables others to potentially inflate their power claims.
