I skimmed that thread and would agree it's been beaten to death. Bottom line is that you will not hurt anything by running a slightly smaller gap. It really comes down to personal preference. I happen to know a few guys in the industry who are pro EFI tuners and with boosted cars spark plug gap to them is only relevant to how much boost a vehicle is making. I will guarantee you that if you push mid to upper 20's or higher in boost you would start to have issues with the spark getting blown out at that high of gap. It's also highly dependent on the tune. Ask anyone who is making over 400whp what spark plug gap they are at. Chances are it's less than .044.
In conclusion run the gap your tuner suggests with your supporting mods.
